Omer Katz c174643b08 cppgc: Implement process-global state accessors. 
Process global accessors for total physical size and used size are
needed for blink. These are implemented via an allocation observer that
atomically updates static counters.

The public api only provides getters for the counters. An internal class
is in charge of updating the counters as needed. A similar split is also
applied to IsAnyIncrementalOrConcurrentMarking().

Drive-by: ProcessHeap is merged into cppgc::internal::WriteBarrier.

C++ Garbage Collection

This directory provides an open-source garbage collection library for C++.

The library is under construction, meaning that all APIs in this directory are incomplete and considered unstable and should not be used.
