x86/CPU/AMD: Add more models to X86_FEATURE_ZEN5 (2024-01-25 12:26:21 +0100)

----------------------------------------------------------------
- Make sure 32-bit syscall registers are properly sign-extended

- Add detection for AMD's Zen5 generation CPUs and Intel's Clearwater
Forest CPU model number

- Make a stub function export non-GPL because it is part of the
paravirt alternatives and that can be used by non-GPL code
