feat(cpufeat): enable FEAT_SVE for FEAT_STATE_CHECKED

Add support for runtime detection (ENABLE_SVE_FOR_NS=2), by splitting
sve_supported() 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 do SVE specific setup.

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