[Driver][XRay][test] Mark these tests as supported on loongarch64

[Ami-zhang]

Summary

Depends on D156089 .

[MaskRay]

Thank you for improving the XRay tests. I have cleaned up some xray tests in June but did not finish the remaining ones. This motivated me to properly fix them. I'll soon remove clang/test/Driver/XRay/lit.cfg.py after we no longer rely on the default target triple.

Thanks @MaskRay .
05c2c09bb1f10261f6f804a2d510c55d97b1584c improved these XRay tests.
Abandon this change.
