Add support for loongarch64
Fix build on linux/loongarch64.
We will need you to sign the CLA. In addition, this should be added to the table in the loader design doc alongside the rest of the platforms.
Also, we tend to follow Debian, who uses loong64 as the architecture name: https://wiki.debian.org/Ports/loong64
I don't think Loongson can sign a Khronos Group agreement due to U.S. sanctions.
@rpavlik PTAL.
@qiangxuhui I think you need a separate commit for change fragment. You can check other merged PRs on GitHub to see what it means.
@utzcoz Done.
An issue (number 2306) has been filed to correspond to this pull request in the internal Khronos GitLab (Khronos members only: KHR:openxr/openxr#2306 ), to facilitate working group processes.
This GitHub pull request will continue to be the main site of discussion.
@rpavlik Done.
