  [IA] Use a single callback for lowerDeinterleaveIntrinsic [nfc] (#148978)

This essentially merges the handling for VPLoad - currently in
lowerInterleavedVPLoad which is shared between shuffle and intrinsic
based interleaves - into the existing dedicated routine.

My plan is that if we like this factoring is that I'll do the same for
the intrinsic store paths, and then remove the excess generality from
the shuffle paths since we don't need to support both modes in the
shared VPLoad/Store callbacks. We can probably even fold the VP versions
into the non-VP shuffle variants in the analogous way.
