Ryan Harrison 6839cba568 Add toggle to control if validity is expected in fuzzer
This toggle controls if the fuzzer will throw a fatal error in the
case that the shader becomes invalid.

Currently the fuzzers do no guarantee that the options that are
provided are correct/valid, so there are many uninteresting cases that
become invalid due to the limited nature of the fuzzers, not due to
bugs in the code. The default off state of this toggle will suppress
this noise.

Once https://bugs.chromium.org/p/tint/issues/detail?id=1356 is
implemented this toggle can be default on.
