Juergen Gross cd95149561 x86/static-call: provide a way to do very early static-call updates ...

commit 0ef8047b737d7480a5d4c46d956e97c190f13050 upstream.

Add static_call_update_early() for updating static-call targets in
very early boot.

This will be needed for support of Xen guest type specific hypercall
functions.

This is part of XSA-466 / CVE-2024-53241.
