[LegalizeVectorTypes] Teach WidenVecRes_Convert to turn ANY_EXTEND into ANY_EXTEND_VECTOR_INREG when the input and output types need to be widened to the same width.

If we don't do it here, DAGCombine will just end up creating it from the scalar any_extend+build_vector so might as well save a step.
