Michael Lippautz 20e1ba2808 cppgc: Move ProcessWeakness into FinishMarking 
For cross-thread handling we require the atomic marking pause to
provide an atomically consistent view of markbits and weak references.
This is ensured by locking the whole atomic pause from entering to
weak processing.

This CL move ProcessWeakness() into FinishMarking() which allows to
nicely scope the upcomming lock from EnterAtomicPause() to
LeaveAtomicPause(). The alternative is requiring the caller to ensure
proper locking which is harder than ensuring that the Marker is
consistent.

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.
