  [RISCV] Move Machine Copy Propagation Pass before Branch relaxation pass (#97261)

Machine Copy Propagation Pass may enlarge branch relaxation distance by
breaking generation of compressed insts. This commit moves Machine Copy
Propagation Pass before Branch relaxation pass so the results of Branch
relaxation pass won't be affected by Machine Copy Propagation Pass.
