Adds allocation-based heap growing strategy that triggers GC based on
some limit. The limit is computed based on previous live memory and a
constant growing factor.
For invoking GC, we support two modes: with and without conservative
stack scanning. Without conservative stack scanning, an invoker makes
sure that we schedule a GC without stack using the existing platform.

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 reverts commit a35d0e8cb5.
The original CL is likely not a culprit for the infra failures.

This moves concurrent and incremental sweeping from Blink. This also
adds TestPlatform that makes it easier to test concurrent and
incremental sweeping.
Drive-by: fix unmarking of large pages.

The category name changed in https://crrev.com/c/2159690 (in
depot_tools), hence presubmit tests start failing whenever someone
touches a file which still refers to the old category.

- Fixes includes to be relative to include/ which allows embedders
to just add V8's include directory to get started.
- Adds public target for the library as "cppgc".

This CL adds basic infrastructure for:
- MakeGarbageCollected
- GarbageCollected and related type traits
- Heap (API / internal)
- Basic allocation based on malloc
- CollectGarbage without marking
This allows for allocation and reclamation through an explicit GC
call. No objects are held alive from any source (stack, globals,
refs), yet.
The exact wiring of platform is future work.

GCInfo and its related infrastructure is used to record information
about types. Currently, we store finalization and vtable information.
Future changes will introduce naming and tracing, similar to Oilpan in
Blink.
Information is stored in a process-wide global table that is
maintained at runtime. For static builds such information can be
recorded in the binary without the runtime overhead which is future
work.
This ports `third_party/blink/renderer/platform/heap/gc_info.{h,cc}`
on a semantic level. In addition to adjusting to V8's needs, we also
re-commit the already filled parts of the info table as read-only when
possible, making it harder to override type information.
