  [RISCV][VLOPT] Add Vector FP instructions to getOperandInfo (#121609)

Although we cannot reduce the VL of these instructions (i.e. add to
isSupported) we can add them to getOperandInfo to enable optimization
where the FP vector instruction are users. Most of the instructions are
covered by existing tests, and I added tests for the narrowing
conversions because I was a little unsure whether the dest or the source
was 2*SEW and 2*LMUL.
