  [msan][NFCI] Generalize handleVectorPmaddIntrinsic() (#166282)

This generalizes `handleVectorPmaddIntrinsic()`:
- potentially handle floating-point type intrinsics (e.g.,
`llvm.x86.avx512bf16.dpbf16ps.512`). This usage is not enabled yet.
- "multiplication with an initialized zero guarantees that the
corresponding output becomes initialized" is now gated by a parameter
