Alastair Donaldson 4d18c6b7c5 spirv-tools fuzzers: Avoid passing target backend
Changes the spirv-tools fuzzer 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 an OSS-Fuzz bug reproducer does not use the required
back-end command line argument.

Vasyl Teliman 0b3611b8c8 Add spirv-tools fuzzer
This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.

The list of all supported CLI arguments and their description is in the cli.h file.
