[GISel][RISCV]Implement indirect parameter passing (#95429)
Some targets like RISC-V pass scalars wider than 2×XLEN bits by
reference, so those arguments are replaced in the argument list with an
address (See RISC-V ABIs Specification 1.0 section 2.1).
This commit implements this indirect parameter passing in GlobalISel.
