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.
