[RISCV] Remove vmv.s.x and vmv.x.s lmul pseudo variants (#71501)
vmv.s.x and vmv.x.s ignore LMUL, so we can replace the PseudoVMV_S_X_MX and PseudoVMV_X_S_MX with just one pseudo each. These pseudos use the VR register class (just like the actual instruction), so we now only have TableGen patterns for vectors of LMUL <= 1. We now rely on the existing combines that shrink LMUL down to 1 for vmv_s_x_vl (and vfmv_s_f_vl). We could look into removing these combines later and just inserting the nodes with the correct type in a later patch. The test diff is due to the fact that a PseudoVMV_S_X/PsuedoVMV_X_S no longer carries any information about LMUL, so if it's the only vector pseudo instruction in a block then it now defaults to LMUL=1.
