  [AMDGPU] Fix DAG types for V_MAD_I64_I32 and V_MAD_U64_U32. NFC. (#123629)

These instructions return a 64-bit result and a 1-bit carry, unlike
smul_lohi and umul_lohi which return a pair of 32-bit results.

This does not appear to make any difference in practice because the DAG
types are not used for anything before these nodes are converted to
MachineInstrs.
