refactor(cpufeat): decouple FGT feature detection and build flags
Split the feature check for FEAT_FGT into two parts:
- A boolean function that just evaluates whether the feature is usable.
This takes build time flags into account, and only evaluates the CPU
feature ID registers when the flexible FEAT_STATE_CHECK method is
used.
- A "raw" function that returns the unfiltered CPU feature ID register.
Change the callers where needed, to give them the version they actually
want.
