This is a reland of 2d087f237e
The changes are :
* Fix redundant reinterpret_cast in test file for MSVC failure
https://crbug.com/v8/12476
* Fix flaky test
https://crbug.com/v8/12475
If a sample is captured during a GC, no embedder context is obtained
defaulting to EMPTY. This is the expected behavior, made it in clear
in implementation and in test.
* Synchronized the embedder context filter behavior with existing
native context filter.

Add APIs to surface VMState and new EmbedderState to CpuProfile samples.
EmbedderState:
* An EmbedderState is defined as a value uint8_t and a v8::context used
for filtering.
* EmbedderStates are stack allocated by the embedder, construction and
destruction set/unset the state to the isolate thread local top.

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.
