Change the unittest runner to no longer uncondtionally set up a default
platform in the "environment", but to instead make platform set-up part
of the "mixin" framework for test fixtures.
Requires modifying some tests that expect the platform to be available,
and all flag implications resolved, before the mixin constructors run.
We still keep the environment for setting up the process for cppgc. This
process setup can only be done once per process, so it can no longer use
the platform -- that's ok though, the page allocator used by cppgc's
process initialisation doesn't have to be the same as the platform's so
we can just pass in a separate new one.

The hello world sample needs to initialize V8's default platform in case
it is not built as stand-alone example.

Use grep to check for obviously unneeded includes. e.g. headers that
include <vector> but does not contain "std::vector".

Both sample are essentially the same up to string constants since
cppgc's default platform started using libplatform.
The only diff between the sample is whether we call
v8::V8::IntializePlatform or cppgc::InitializeProcess.
Drive-by: replace CPPGC_BUILD_IN_V8 with CPPGC_IS_STANDALONE which is
more descriptive.

This CL adds tracing scopes for the various cppgc classes.
Scopes use TRACE_EVENT_BEGIN and TRACE_EVENT_END macros to report trace
events. To do so they need to include trace-event.h. For unified heap
builds, trace-event.h forwards to v8's src/tracing/trace-event.h. For
other builds, trace-event.h provides a subset of
src/tracing/trace-event.h that covers just the parts used by cppgc.
This CL covers what we need for traces and blink gc metrics (up to
renaming events from BlinkGC.* to CppGC.*). UMA and UKM are not yet
handled.

For the standalone library, some platform implementations might not
support non-nested tasks. We can still offer incremental marking in
such cases using regular tasks and without assuming an empty stack.
(cppgc's default platform e.g. doesn't support non-nested tasks.)
This CL also updates GCInvoker to not trigger an incremental GC if we
won't be able to finalize it. That makes finalizing through an
non-nested incremental task safe.
