  [RISCV] Eliminate getVLENFactoredAmount and expose muladd [nfc] (#87881)

This restructures the code to make the fact that most of
getVLENFactoredAmount is just a generic multiply w/immediate more
obvious and prepare for a couple of upcoming enhancements to this code.

Note that I plan to switch mulImm to early return, but decided I'd do
that as a separate commit to keep this diff readable.
