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.

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.

This is instead of consuming a portion of the input, so that the seed
corpus of valid shaders can be more effective.

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.
