[RFC gcc13 backport 0/3] Add Ztso atomic mappings

[Patrick O'Neill]

I vaugely recall some discussion about backporting the Ztso mappings
along with the RVWMO mappings. Now that the RVWMO mappings have been
backported for 13.3, is there interest in also backporting the Ztso
mappings?

Tested using for regressions using rv32gc/rv64gc glibc.
