Remove TextBlob's empty mailbox in favor of delegate

The empty mailbox is a bit awkward with a buffet build because
the client would have to select the "empty" implementation
or incur link errors from SkTextBlob.cpp

This has the gpu backend register a callback function to be
invoked when the textblob is being destroyed.
