Andre Przywara ea735bf556 refactor(cpufeat): enable FEAT_VHE for FEAT_STATE_CHECKED
At the moment we only support FEAT_VHE to be either unconditionally
compiled in, or to be not supported at all.

Add support for runtime detection (ENABLE_FEAT_VHE=2), by splitting
is_armv8_1_vhe_present() into an ID register reading function and a
second function to report the support status. That function considers
both build time settings and runtime information (if needed), and is
used before we access VHE related registers.
Also move the context saving code from assembly to C, and use the new
is_feat_vhe_supported() function to guard its execution.

Enable VHE in its runtime detection version for all FVP builds.
