crrev.com/875699 introduced gin::InitializeCppgcFromV8Platform(), which
centralized initialization of cppgc in Gin for the case of multiple
cppgc users in the same process.
Introduce gin::MaybeShutdownCppgc(), which centralizes the shutdown of
cppgc in Gin. This will help in guaranteeing that cppgc is shutdown only
after all users in the same process are done using it.
