Instead of moving the stand-alone logic to the base heap, allows
specific heaps to override their stand-alone GC behavior. This allows
CppHeap to reuse the unified heap bottlenecks and visitors for
testing. This works as long as any v8 references are empty as there is
no Isolate attached to the heap in this case.

cppgc/testing.h is already part of a testonly gn target which only can
be included from other test targets. This prevents any production
target to depend on cppgc/testing.h.

Adds testing API that can only be used after enabling it on a heap.
The call that enables testing is only provided via v8_for_testing or
cppgc_for_testing build targets which protects against misusing from
production code.
