Jan Beulich bd630bbdd4 x86: SHADOW_PAGING is deprecated ...

Addressing certain issues, in particular related to operations which may
take excessively long and therefore would need preemption, has turned out
overly costly. Since alternatives (HVM/PVH: HAP, PV: shim) are commonly
available, the decision was to deprecate the functionality, while still
retaining it for people to use at their own (security) risk. Memory-wise
small enough guests may still be okay to run.

Some CI testing depends on SHADOW_PAGING.  Explicitly enable it when needed.

This is CVE-2026-42493 / XSA-495.
