aarch64: Optimize __libc_mtag_tag_region
This is a target hook for memory tagging, the original was a naive implementation. The optimized version relies on "dc gva" to tag 64 bytes at a time for large allocations and optimizes small cases without adding too many branches. This was not benchmarked on real cpu, but expected to be faster than the naive implementation.
