Existing translations are either from MLIR or to MLIR. To support cases like round-tripping some external format via MLIR, one must chain two mlir-translate invocations together using pipes. This can be problematic to support -split-input-file in mlir-translate given that it won't work across pipes. Motivated by the above, this CL adds another translation category that allows file to file. This gives users more freedom. PiperOrigin-RevId: 269636438
