cb082a6026 [platform] Provide NewDefaultJobHandle function
This will allow embedders to actually instantiate the {DefaultJobHandle}
as suggested in the comment. Node currently implements {PostJob()} by
just returning a nullptr. After this change, it can use the new
{NewDefaultJobHandle} function and we can actually start using this API
in v8.

9dbab9bbdb [tracing] Migrate tracing to Perfetto track events
This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT
macros) with the track event base implementation from Perfetto. The
advantages of doing this are:

1) This allows us to remove most tracing-related backend code from V8.

2) V8 can start writing strongly typed trace event arguments, which
   are more compact, easier to process and more extensible than legacy
   JSON-based trace arguments.

For the time being, we still support the old trace macros when V8 is
embedded into Chrome and other embedders.

f83b1b3beb [tracing] Fix endianness problem when using booleans
All the data types defined under ArgValue are 8 bytes
expect "bool as_bool". When casting to <uint64_t> under
"tracing/trace-event.h", boolean gets placed on the lower
byte of the memory on LE, and on the higher byte on BE machines.
When using a "Union" to read back the value as a boolean, only
the lower byte of the memory location is read which makes it
fine on LE machines, however the value will not be present on BE
machines.

Using an 8 byte data type as boolean will assure the entire filed
is read instead of only the lower byte.

739bee71fa [api] Use C++14 [[deprecated]] attribute
Since C++14, there is a spec'ed attribute for deprecation of methods,
functions, types, aliases or anything else.
This CL switches from the GCC __attribute__ to this standard attribute.
This allows to use the V8_DEPRECATED and V8_DEPRECATE_SOON macros on
anything where the standard attribute can be used (including {using}
statements that were not working before). It also avoids the need to
nest the whole declaration in the macro, making the code more readable.

5ab7510e93 [tracing] Fix TracingCpuProfiler test for Perfetto
Update the TracingCpuProfiler test to work properly with perfetto.

Roll perfetto to get fixes for bugs encountered with starting/stopping
tracing rapidly, which happens in the test for the tracing profiler.

Add a check that the DataSource::Register call was successful to flush
out any errors there (although they are fixed by the perfetto roll).

Emit a fake trace event when stopping tracing in order to avoid
losing the final trace event that the user provided. Remove the ad-hoc
fake final trace events that the cctests for perfetto added.

Add a test StartAndStopRepeated which flushes out the issues fixed by
the perfetto roll.

edd383fbcd [tracing] Use the new perfetto client API
The client API provides a much simpler interface so that we don't have
to deal with producers, consumers etc. directly. This CL removes all the
code that dealt with the more complex API used previously.

The architecture used here requires that the embedder call into
Tracing::Initialize() to set up the tracing backend. The tracing
controller then connects to this backend when calling
DataSource::Register() and Tracing::NewTrace(). This will ultimately
avoid the need for a virtual call (or two) for every trace event that
need to be dispatched over the API - chrome can provide a backend
and V8 will connect to it opaquely with the same code when tracing is
enabled.

d365f62ec1 [tracing] Add a way to test perfetto traces.
Add a new abstract class TraceEventListener which is just an interface
for consuming trace events. This separates the V8-specific stuff that
an actual perfetto consumer needs to do e.g. handling the has_more flag
and signalling back to the controller with a semaphore.

This is a change from the previous plan of making the PerfettoConsumer
class sub-classable to implement custom consumption of trace events.
This will be difficult when the consumer is created outside of the
PerfettoTracingController as we can't hook up the
consumer_finished_semaphore_ that belongs to the controller.

Now the PerfettoTracingController is responsible for the Consumer life-
cycle and hides it entirely from callers. We add the
AddTraceEventListener() method to allow callers to register a listener
either for testing or a JSON listener for real tracing.

This lets us write tests that can store all the trace events in memory
without first converting them to JSON, letting us write test more
easily. There's an example test add to test-tracing - more tests using
this style will follow.

8f4063c6ea [tracing] Implement the default TracingController with Perfetto
Based on Primiano's prototype:
https://chromium-review.googlesource.com/c/v8/v8/+/1290549

This is still behind a build flag. I'll add functionality incrementally
rather than land everything in one giant CL.

This CL sets up the basic classes that will be used for the Perfetto
implementation, e.g. the producer, consumer, controller and task runner.

This implementation produces a binary proto file in the current
directory named v8_trace.proto. It doesn't yet produce JSON output,
that is coming in a following CL.

Currently the old tracing and perfetto tracing are both run alongside
each other if the build flag is enabled.

51e80efd12 [tracing] Fix races in TracingController implementation
The default TracingController (used by d8 and Node) has some concurrency
issues. The new test flushes these out, when a second thread logs trace
events while the main thread calls StopTracing().

- Use an acquire load in UpdateCategoryGroupEnabledFlags() because this
  was racing with GetCategoryGroupEnabled() where a new category is
  added in the slow path. g_category_groups is append-only, but
  reads/writes to g_category_index need to be correctly ordered so that
  new categories are added and only then is the change to the index
  visible. The relaxed load ignored this and caused unsynchronized
  read/write.
- Use a relaxed load in ~ScopedTracer() to access category_group_enabled
  as this previously used a non-atomic operation which caused a race
  with UpdateCategoryGroupEnabledFlag() which does a relaxed store.
- Replace TracingController::mode_ with an atomic bool as read/writes to
  mode_ were not synchronized and caused TSAN errors. It only has two
  states and it doesn't seem like we will extend this so just convert it
  to bool.
- Take the lock around calling trace_object->Initialize in
  AddTraceEvent(), and around trace_buffer_->Flush() in StopTracing().
  These two raced previously as the underlying TraceBufferRingBuffer
  passes out pointers to TraceObjects in a synchronized way, but the
  caller (AddTraceEvent) then writes into the object without
  synchronization. This leads to races when Flush() is called, at which
  time TraceBufferRingBuffer assumes that all the pointers it handed out
  are to valid, initialized TraceObjects - which is not true because
  AddTraceEvent may still be calling Initialize on them. This could be
  the cause of issues in Node.js where the last line of tracing/logging
  sometimes gets cut off. This is kind of a band-aid solution - access
  to the TraceObjects handed out by the ring buffer really needs proper
  synchronization which at this point would require redesign. It's quite
  likely we will replace this with Perfetto in the near future so not
  much point investing in this code right now.
- Enable TracingCpuProfiler test which was flaky due to these bugs.

69040ced45 [api] Disable in_process_stack_dumping in DefaultPlatform by default.
This flips the default value of in_process_stack_dumping from enabled
to disabled. For many embedders the V8 signal handler produces worse
stack trace than the defaul signal handler.

9bacf52359 [cleanup] Deprecate EnsureEventLoopInitialized
Due to a recent refactoring the function EnsureEventLoopInitialized on
the default platform became obsolete. It does not contain a single line
of code. With this CL we prepare the removal of this function from the
V8 platform API.

ffee558e14 [cleanup] use unique_ptr for the DefaultPlatform
With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate
that the caller owns the returned memory. We had several memory leaks
where the memory of the DefaultPlatform did not get deallocated.

In addition, the {TracingController} of the {DefaultPlatform} also gets
received as a unique_ptr. Thereby we document that the {DefaultPlatform}
takes ownership of the {TracingController}. Note that the memory of the
{TracingController} was already owned by the {DefaultPlatform}, but it
was not documented in the interface, and it was used incorrectly in
tests.

This CL fixes the asan issues in

de964dbe57 Introducing an event loop mechanism for d8.
This mechanism ensures APIs like wasm async complete their work, 
without requiring use of natives (%APIs).

The mechanism is similar to the one used in content_shell,
which should allow us to easily port tests in that environment.
