tools headers UAPI: Sync arch prctl headers with the kernel sources
To pick the changes in this cset:
a03c376ebaf38394 ("x86/arch_prctl: Add AMX feature numbers as ABI constants")
23e5d9ec2bab53c4 ("x86/mm/iommu/sva: Make LAM and SVA mutually exclusive")
2f8794bd087e7958 ("x86/mm: Provide arch_prctl() interface for LAM")
This picks these new prctls in a third range, that was also added to the
tools/perf/trace/beauty/arch_prctl.c beautifier.

With this 'perf trace' can translate those numbers into strings and use
the strings in filter expressions:

This addresses this perf build warning:
Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/prctl.h' differs from latest version at 'arch/x86/include/uapi/asm/prctl.h'
