  [SDAG] Split the partial reduce legalize table by opcode [nfc] (#141970)

On it's own, this change should be non-functional. This is a preparatory
change for https://github.com/llvm/llvm-project/pull/141267 which adds a
new form of PARTIAL_REDUCE_*MLA. As noted in the discussion on that
review, AArch64 needs a different set of legal and custom types for the
PARTIAL_REDUCE_SUMLA variant than the currently existing
PARTIAL_REDUCE_UMLA/SMLA.
