string: add __mtag_tag_zero_region
Add optimized __mtag_tag_zero_region(dst, len) operation to AOR. It tags
the memory according to the tag of the dst pointer then memsets it to 0
and returns dst. It requires MTE support. The memory remains untagged if
tagging is not enabled for it. The dst must be 16 bytes aligned and len
must be a multiple of 16.
Similar to __mtag_tag_region, but uses the zeroing instructions.
