The macro list makes it difficult to impossible to deprecate individual
methods (like the one receiving a {WasmModuleTieredUp} struct).
Hence avoid the macro list and instead call the macro explicitly for
each definition.

The CL makes sure to extract and copy Oilpan young GC metrics to
v8::metrics::GarbageCollectionYoungCycle. In addition, it makes sure
that metrics are not reported twice by bailing out from
GCTracer::NotifyCppGCCompleted() for young GC cycles (the metrics are
reported later in Heap::CollectGarbage() by calling
GCTracer::StopCycle()).

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.

As part of an effort to prepare the Recorder interface for general use,
we had to make some changes to the way the existing Wasm Events are
being used. In particular,
- it is more fitting to use a ElapsedTimer than a TimedScope to
measure the durations in src/wasm/module-[decoder|instantiate].cc
- we want to rename the wall_clock_time_in_us field to duration_in_us
for clarity.
Because these Wasm events are already being instantiated in chromium,
renaming the field requires a two-step change. This is the first of
those changes.

Chrome is currently adding a 128-bit V8ContextToken to keep track of
V8 contexts across multiple isolates and processes. Having per-isolate
token exposed by V8 leads to confusion of these two tokens.
This moves v8::Context::Token to v8::metrics::Recorder and changes
the corresponding functions:
- v8::Context::GetToken => v8::metrics::Recorder::GetContextId
- v8::Context::GetByToken => v8::metrics::Recorder::GetContext
This CL is purely mechanical and does not change the behaviour.
