  [Hexagon] Add lowering for `{max,min}num` (#202938)

Since the floating point requirements for `{max,min}num` are less strict
than the ones for `{max,min}imumnum`, it is fine to lower them to the
same instructions that already meet the requirements for the latter.
This is similar to what the RISC-V backend does for example.

This is also a lot better than generating a standard library call.
