Add AT_RSEQ_* from Linux 6.3 to elf.h
Linux 6.3 adds constants AT_RSEQ_FEATURE_SIZE and AT_RSEQ_ALIGN; add them to glibc's elf.h. (Recall that, although elf.h is a system-independent header, so far we've put AT_* constants there even if Linux-specific, as discussed in bug 15794. So rather than making any attempt to fix that issue, the new constants are just added there alongside the existing ones.) Tested for x86_64.
