[ARM] Extend narrow values to allow using truncating scatters
As a minor adjustment to the existing lowering of offset scatters, this
extends any smaller-than-legal vectors into full vectors using a zext,
so that the truncating scatters can be used. Due to the way MVE
legalizes the vectors this should be cheap in most situations, and will
prevent the vector from being scalarized.
