Scopes in V8 are used to guarantee one or more properties during its
lifetimes. If a scope is not named e.g MyClassScope(args) instead of
MyClassScope scope(args) it will get created and automatically destroyed
and therefore, being useless as a scope. This CL would produce a
compiling warning when that happens to ward off this developer error.
Follow-up to ccrev.com/2552415 in which it was introduced and
implemented for Guard classes.

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.

in debug builds and in never-cancelled tasks in release builds.

Split platform into a process-global initialization part and per-heap
platform objects.
These platform objects still contain allocators and executors. With
per-heap platforms GetForegroundTaskRunner() returns by definition the
correct runner.
In future, when initialized throuhg V8, an adapter can be used to
translate between the different platforms, avoiding the needed for V8
embedders to provide additional information.

This moves concurrent and incremental sweeping from Blink. This also
adds TestPlatform that makes it easier to test concurrent and
