This is a reland of d1b27019d3
Fixes include:
Adding missing file to bazel build
Forward-declaring classing before friend-classing them to fix win/gcc
Add missing v8-isolate.h include for vtune builds

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.

A pointer-compressed heap has the same heap limit heuristics as a 32-bit
heap. Specifically, the heap limit is restricted to 1GB due to scarce
virtual addresses space on 32-bit platforms. That limitation does not
apply for pointer-compressed heaps which can use 4GB.
This CL changes the heap limit computation to use system the pointer
size instead of the tagged pointer size. Note that the young generation
limit continues to use the tagged pointer size.

The new API function is called ConfigureDefaultsFromHeapSize and
accepts two parameters: the initial and the maximum heap size.
Based on the given limits the function computes the default size
for the young and the old generation.
The patch also cleans up the existing functions to make them
consistent in terms of units and heap structure.
