[MLIR/XLA] A round of renames for HLO and LHLO dialects.

Updates InterpreterOptions, TensorShape, and TensorDataType to be nested types.

Exclude python so that the generator doesn't recurse into it.

Automated rollback of commit dcb8aa7d83cad848473b99f66146b48e8eb26d50

Changed return type of ByteCount() to int64_t for convergence between internal/external protobuf.
