Adds a new flag v8_deprecate_get_isolate that marks
HeapObject::GetIsolate/GetHeap, Handle<T>(T*) and handle<T>(T*) as
[[deprecated]]. Deprecation warnings are not converted to errors so an
entire build can be completed to collect all the warnings.
Also adds a new script tools/collect_deprecation_stats.sh which runs the
build (assuming the flag is set) and collects the number of uses of
deprecated functions. E.g. at the time of upload, we get:
Total deprecated calls: 2265
515 GetHeap
842 GetIsolate
210 handle
698 Handle
