  [RISCV][GISel] Remove support for s32 G_VAARG on RV64. (#102533)

Part of making s32 not legal for RV64. Unfortunately, generic
widening/narrowing is not implement for this operation so I had to
remove all tests.

I don't think clang uses G_VAARG on RISC-V so this shouldn't be a big
deal in practice.
