[Local GC] Use standard C++ types (bool) and consistent types (void*) on the interface (dotnet/coreclr#10463)

* [Local GC] BOOL -> bool on IGCHeap

* [Local GC] size_t -> void* on IGCHeap

* [Local GC] Silence warnings by being explicit about BOOl -> bool conversions

* Address code review feedback: FinalizeAppDomain BOOL -> bool

* Fix warnings

* Address code review feedback:
  1) Fix a missed default parameter (FALSE) on a parameter of type bool,
  2) Fix invocations of the diagnostic callbacks to use boolean literals
     instead of TRUE and FALSE,
  3) Fix various invocations of GC interface methods in the VM to use
     boolean literals instead of TRUE and FALSE

* Address code review feedback: fix inconsistency
