Andre Przywara 6503ff2910 refactor(cpufeat): enable FEAT_RAS for FEAT_STATE_CHECKED
At the moment we only support FEAT_RAS to be either unconditionally
compiled in, or to be not supported at all.

Add support for runtime detection (FEAT_RAS=2), by splitting
is_armv8_2_feat_ras_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 RAS related registers.

Also move the context saving code from assembly to C, and use the new
is_feat_ras_supported() function to guard its execution.

Change the FVP platform default to the now supported dynamic
option (=2), so the right decision can be made by the code at runtime.
