[fuzz] Add heuristic file type check for single inputs Attempt to determine if the input matches the expected type for the fuzzing mode, text for WGSL and binary for IR, by looking for invalid control characters in the input or nulls. Includes an escape hatch for when there is false positives An alternate that was considered was to check for is valid UTF-8, since that is what WGSL shaders are. But that would mean that test cases that intentionally create malformed text would raise false positives.
