  [RISCV][GISel] Sink getOperandsMapping call out of the switch in getInstrMapping. (#72326)

Use a SmallVector of `ValueMapping *` that we populate in the switch for
each register operand. The entry in the SmallVector defaults to nullptr
for each operand so we don't need to write explicit `nullptr` in the
cases.

After this we can generically fill in GPR for registers as a default
case and remove some opcodes from the switch.
