x86/mm: Redefine some of page table helpers as macros

This is preparation for the next patch, which would change
pgtable_l5_enabled to be cpu_feature_enabled(X86_FEATURE_LA57).

The change makes few helpers in paravirt.h dependent on
cpu_feature_enabled() definition from cpufeature.h.
And cpufeature.h is dependent on paravirt.h.

Let's re-define some of helpers as macros to break this dependency loop.
