[AArch64][GlobalISel] Add combine for build_vector(unmerge, unmerge, undef, undef) (#165539)
This PR adds a new combine to the `post-legalizer-combiner` pass. The
new combine checks for vectors being unmerged and subsequently padded
with `G_IMPLICIT_DEF` values by building a new vector. If such a case is
found, the vector being unmerged is instead just concatenated with a
`G_IMPLICIT_DEF` that is as wide as the vector being unmerged.
This removes unnecessary `mov` instructions in a few places.
