[3.0] contrib: ass: Apply a patch to fix aarch64 assembly issues
This fixes building for aarch64 Windows with assert enabled versions of Clang. (This issue appeared recently, after updating to a newer version of libass that includes new aarch64 assembly.)
The same patch has been sent upstream in https://github.com/libass/libass/pull/849.
(cherry picked from commit 44710998)
