on recent Intel CPU with waitpkg feature

there is a dependency of the vmx feature vmx-enable-user-wait-pause on
waitpkg

however this dependebcy is wrongly expressed in Noble with the origial commit:
https://github.com/qemu/qemu/commit/33cc88261c352445d31599054653d759f20531c1

this has been fixed:
https://github.com/qemu/qemu/commit/2b956256439ecf02327f088a050c9c9fcca00b55

so in Noble, with a VM that has waitpkg, if it does not have 
vmx-enable-user-wait-pause, the feature is disabled.
that makes the migration  from old release (jammy in this case) impossible 
because jammy detects waitpkg but but not yet vmx-enable-user-wait-pause.

migrations from jammy to jammy is OK
migrations from noble to noble and newer (questing/resolute) is OK
