KVM: selftests: Refactor X86_FEATURE_* framework to prep for X86_PROPERTY_*

Browse source

Refactor the X86_FEATURE_* framework to prepare for extending the core
logic to support "properties".  The "feature" framework allows querying a
single CPUID bit to detect the presence of a feature; the "property"
framework will extend the idea to allow querying a value, i.e. to get a
value that is a set of contiguous bits in a CPUID leaf.

Opportunistically add static asserts to ensure features are fully defined
at compile time, and to try and catch mistakes in the definition of
features.

No functional change intended.
