Most of these aren't needed anymore.

We should probably be consistent and use EnterResource. In truth, neither of
them locks in the in-process implementation.

But if we ever do try to support multi-threading for in-process plugins, we
would probably want to lock here to protect against the input_event PP_Resource
disappearing out from under us.

Done.
