This patch adds support for the new SME LUTv2 architecture extension as
described in the ACLE. It adds the `+sme-lutv2` target flag, the
`__ARM_FEATURE_SME_LUTv2` feature test macro and the `svluti4_zt`,
`svwrite_lane_zt` and `svwrite_zt` intrinsics. Making use of the new
instructions without the intrinsics will be done in a follow up patch.
Testing done:
`make check-gcc` and `make check-target` pass.
ChangeLog:
