[AArch64] Fold away zext of extract of uzp. (#107367)
Similar to #107201, this comes up from the lowering of zext of
deinterleaving shuffles. Patterns such as ext(extract_subvector(uzp(a,
b))) can be converted to a simple and to perform the extract/zext from a
uzp1. Uzp2 can be handled with an extra shift, and due to the existing
legalization we could have and / shift between which can be combined in.
Mostly this reduces instruction count or increases the amount of
parallelism in the sequence.
