Igor Sheludko e74e6c524c [cppgc] Rename src/heap/cppgc/ to src/heap/cppgc-internal/
Rename the internal cppgc directory to src/heap/cppgc-internal/ to
clearly distinguish it from the public include/cppgc/ headers and
avoid potential naming confusion.
The collision occurs on Windows builds where -Wmicrosoft-include
is enabled by Clang in MSVC compatible mode. MSVC on Windows uses
different order of directories where the files are searched by the
compiler and `#include "cppgc/blah.h"` in public headers might end up
including "src/heap/cppgc/blah.h" if it exists.

All internal #include paths, include guards, and build configurations
(BUILD.gn and BUILD.bazel) have been updated to reflect the new path.

Michael Achenbach 66253e1b99 [build] Use a new google_benchmark location to avoid conflicts
Using the same path for DEPS'ed and previously checked-in files
causes conflicts when going back and forth between new and old
revisions. Since all references here are v8 stand-alone, the
exact location shouldn't be important. Therefore we use some
new name to avoid conflicts when locally running `gclient sync`.

Michael Lippautz a2cf158ad4 cppgc-js: Report C++ memory to V8's heap growing
Add reporting of C++ memory to V8's heap growing strategy via
existing EmbedderHeapTracer interface.

In addition, introduce API-level NoGarbageCollectionScope which
allows to temporarily avoid scheduling GC finalizations. Replace
internal NoGCScope with NoGarbageCollectionScope and remove
NoGCScope.

Omer Katz 0e0d1b0d7c cppgc: Fix cppgc build
The CPPGC_BUILD_IN_V8 define (used for tracing) isn't propagated from
v8_base_without_compiler to cppgc_base, which breaks build with
perfetto. Instead use a gn args to specify standalone builds (defaulted
to false) and use that to choose the right tracing implementation.

bitmap.

The CL also removes the mixin macros which are now no longer needed.
