This CL also adds missing API coverage to the Inspector fuzzing code.
Errors found with the Inspector are now reported as fuzzer failures

This makes it possible to build the fuzzer in Chromium's asan builder

Changes various fuzz targets so that the target back-end language (HLSL,
MSL, SPIR-V or WGSL) is no longer passed as a command line argument, but
instead baked into the fuzzer's binary. This avoids a problem whereby a
ClusterFuzz bug reproducer does not use the required back-end command
line argument.
