[GISel][RISCV] Legalize `G_{U|S}DIVREM` (#93067)
This patch expands `G_{U|S}DIVREM` into `G_{U|S}DIV + G_{U|S}REM`.
`G_{U|S}DIVREM` is generated by the following fold:
https://github.com/llvm/llvm-project/blob/4ea21a0261cd8599a9ffa15f5c554ab0d4bbbe27/llvm/lib/CodeGen/GlobalISel/CombinerHelper.cpp#L1410-L1471
It always folds `div + rem` pairs into `divrem` during pre-legalization.
I tried to change `isLegalOrBeforeLegalizer` to `isLegal`, but it
produced worse codegen on AArch64.
