Brendon Tiszka d0b284b00b Add Dawn Wire Server LPM Fuzzer [1/N]
Add scaffolding for structured Dawn wire fuzzer.

This CL contains a basic fuzzer for Dawn wire server
that shows some simple design ideas:

1) A basic protobuf spec that is generated using dawn.json
2) conversion from protobuf message to a dawn wire server
command.

This is not the complete implementation and serves as a
foundation for the fuzzer so that subsequent CLs will be
easier to review.
