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.
