The interpreter is not an execution tier in production any more. It's
only used in tests.
Thus, remove {ExecutionTier::kInterpreter} and instead add a
{TestExecutionTier} that still has {kInterpreter}.
If needed (in {TestingModuleBuilder::execution_tier()}), we translate
back from {TestExecutionTier} to {ExecutionTier} (for {kLiftoff} and
{kTurboFan} only).
The {TraceMemoryOperation} method, which is shared between interpreter
and production code, now receives a {base::Optional<ExecutionTier>}, and
we will just pass en empty optional if called from the interpreter.

Change the heuristics for OSRing in TurboProp. Currently we OSR if
a funciton is already optimized / marked for optimization but is still
running optimized code. Since TurboProp optimizes much earlier than
TurboFan using the same heuristics would cause us to OSR more often
than required. This cl adds an additional check on the number of ticks
to make sure the function is hot enough for OSRing.

PagedSpace::SizeOfObjects() then returns exactly the same value as
PagedSpace::Size(). SizeOfObjects() used to deduct the current LAB,
however this is now more difficult with local heaps. Accessing the
main thread LAB from concurrent threads causes a data race. Also
LocalHeaps have their own LAB, which should be deducted as well to be
uniform with the main thread. However this would be tricky and expensive.
The simpler solution is to do not deduct the main thread LAB anymore.

With the new Turbofan variants (NCI and Turboprop), we need a way to
distinguish between them both during and after compilation. We
initially introduced CompilationTarget to track the variant during
compilation, but decided to reuse the code kind as the canonical spot to
store this information instead.
Why? Because it is an established mechanism, already available in most
of the necessary spots (inside the pipeline, on Code objects, in
profiling traces).
This CL removes CompilationTarget and adds a new
NATIVE_CONTEXT_INDEPENDENT kind, plus helper functions to determine
various things about a given code kind (e.g.: does this code kind
deopt?).
As a (very large) drive-by, refactor both Code::Kind and
AbstractCode::Kind into a new CodeKind enum class.

Use the new jobs API for WebAssembly compilation. This avoids having to
schedule as many background tasks as there are worker threads. Instead
the one job specifies the maximum concurrency, which changes dynamically
as new compile jobs become available.
This also avoids the artificial deadline we used to ensure that other
tasks get some share of the CPU resources if needed.
Even though this CL moves actual wasm function completely over to the
Jobs API, other similar tasks (like wrapper compilation) are still using
the Task API and need to be ported in a follow-up CL.
Also, we are still using the same priority for baseline compilation and
tier up. We should split this in a follow-up CL to have two jobs with
different priorities. This will also allow us to only block on baseline
compilation where we currently block on both.

A minor refactoring to the logic for triggering callbacks:
1. If compilation failed, do only trigger the kFailedCompilation event.
2. Use the TriggerCallbacks method also for triggering the
kFailedCompilation event.

The DevTools front-end uses so-called Wasm evaluator modules to get to
the values of variables in scope when the wasmDWARFDebugging experiment
is turned on. We rely on the `Debugger.executeWasmEvaluator()` method in
the Chrome DevTools Protocol (CDP) to accomplish this, which in turn is
controlled by this global flag.
Since we intend to gather more feedback from selected internal /
external teams on the DWARF debugging experience, we need to ship this
flag by default to make it easier to test the new experiment without
having to fiddle with additional flags to pass to Chrome on the command
line (and asking folks whether they really started Chrome correctly).
