  -----------
  [RISCV] Add SEW to RISCVInversePseudoTable

Now that scheduler resources are split by SEW for some instructions,
add the ability to map (BaseInstr, LMUL, SEW) -> Pseudo. For
BaseInstrs that are not split by SEW, 0 is the default key.

This does not change the size of the table since there was an 8
bit hole.

  Log Message:
  -----------
  [llvm-mca][RISCV] Add RISCV-SEW instrument

Now that RISCV pseudo instructions now account for SEW in some cases,
it useful that RISCV SEW instruments exist so that llvm-mca can use
the SEW specific scheduler classes.
