Create common utility class for fuzzing

Browse Source 
This moves the usage of Tint in the fuzzers into a single class. This
will be expanded in the future to support emitting shaders, so fuzzing
tests, just need to indicate which reader & writer they want to use,
instead of having each test implement all of the API usage logic
directly.
