Reland "Enable the new GC metrics""

This reverts commit e6e7c93141bde9fcd434c49fd4104c8324184dd8.

The diff between PS1 and PS3 contains fixes for two issues:
1) A standalone CppGC may happen on workers.
2) The start of V8 incremental marking may complete CppGC sweeping of
   the previous GC cycle.
