[SDAG] Support expanding `FSINCOS` to vector library calls (#114039)
This shares most of its code with the scalar sincos expansion. It allows
expanding vector FSINCOS nodes to a library call from the specified
`-vector-library`. The upside of this is it will mean the vectorizer
only needs to handle the sincos intrinsic, which has no memory effects,
and this can handle lowering the intrinsic to a call that takes output
pointers.
