  [MIPS] Fix the opcode of max.fmt and mina.fmt (#85609)

- The opcode of the mina.fmt and max.fmt is documented wrong, the
  object code compiled from the same assembly with LLVM behaves
  differently than one compiled with GCC and Binutils.
- Modify the opcodes to match Binutils. The actual opcodes are as
follows:

  {5,3} | bits {2,0} of func
           |    ...   | 100  | 101    | 110   | 111
  -----+-----+-----+-----+-----+-----
   010  |   ...   |  min  | mina | max  | maxa
