[RISCV][GISel] Remove s32 support on RV64 for DIV, and REM. (#102519)
Based on experience with SelectionDAG and experimental-rv64-legal-i32, I
don't believe making s32 a legal type is viable without introducing an
invariant that s32 values are always sign extended like Mips64 does.
Mips64 does this with a separate 32-bit register class.
`experimental-rv64-legal-i32` was removed in ##102509.
This patch is part of a series to remove s32 support so we can remove
the isel patterns that SelectionDAG is no longer using. To restore code
quality, we will need to add custom W nodes like SelectionDAG.
