spirv-fuzz: Improve debugging facilities (#3074)
Adds an option to run the validator on the SPIR-V binary after each
fuzzer pass has been applied, to help identify when the fuzzer has
made the module invalid.  Also adds a helper method to allow dumping
of the sequence of transformations that have been applied to a JSON
file.
