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.

James Price 5910ec1e8a Output WGSL instead of SPIR-V in transform fuzzers
Generating SPIR-V can cause validation failures when out-of-bounds
accesses are performed, since we are not running the robustness
transform.

Antonio Maiorano 15e89fa7b7 Add '-tint_dump_input=true/false' to fuzzers to dump input spv/wgsl to a file
When enabled, the input spv/wgsl is dumped to a file named
"fuzzer_input_<hash of file>.spv/wgsl".

Note that this adds the setting to all the fuzzers in the root of
fuzzers/, but not to tint_ast_fuzzer, tint_regex_fuzzer, nor
tint_spirv_tools_fuzzer as they currently to their own CLI parsing.

Ryan Harrison a810d71df5 Make params for FirstIndexOffset fuzzing dynamic
The preamble size in tint_all_transforms_fuzzers is dynamic in
anticipation of more complex preamble calculations in future CLs.
