x86/cpuid: Compile out unused logic/objects

CPUID Policy objects are large (1860 bytes at the time of writing), so
compiling them out based on CONFIG_{PV,HVM} makes a lot of sense.

This involves a bit of complexity in init_domain_cpuid_policy() and
recalculate_cpuid_policy() as is_pv_domain() can't be evaulated at compile
time.
