This commit enhances the aarch64 backend with support for SVE2p3 and SME2p3 dot product intrinsics. These additions allow developers to utilize advanced vector processing and streaming capabilities for performing dot product operations, particularly on narrower data types with potential for higher throughput. The changes include updates to intrinsic definitions, machine description patterns, and target flags.
