Alastair Donaldson 8f780f1022 Choose black-box fuzzer back-end based on data
Instead of uploading separate black-box fuzzers for each target
language, it will be more convenient to have the target language chosen
based on the data file being processed. This change facilitates that.

Alastair Donaldson 8b2181c98f Change injected failure from assert to abort
An assertion failure had been injected to check that black box fuzzing
is working, but as ClusterFuzz runs a release mode build this was not
triggering. This change turns the assertion failure into an abort. Once
it has been established that the abort is triggered by the black box
fuzzers, it should be removed.

Alastair Donaldson ac958bd1dd Injected failure in fuzzer target
To test whether black-box fuzzing is working, this change injects an
assertion failure into tint_black_box_fuzzer_target. Once it has been
established that this failure is found by the black box fuzzers, it
should be removed.

Ryan Harrison a617d0f0fc Convert fuzzer to generating configuration data
This is instead of consuming a portion of the input, so that the seed
corpus of valid shaders can be more effective.

Alastair Donaldson 3e70f3e2ac Add black box fuzzer target
Adds a stand-alone executable that serves as an entry point for black
box fuzzing. It reads data from a given file, and then calls into the
same code that the libFuzzer fuzzer targets do.
