At the moment we only support FEAT_MPAM to be either unconditionally compiled in, or to be not supported at all. Add support for runtime detection (ENABLE_MPAM_FOR_LOWER_ELS=2), by splitting get_mpam_version() 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 MPAM related registers. Also move the context saving code from assembly to C, and use the new is_feat_mpam_supported() function to guard its execution. ENABLE_MPAM_FOR_LOWER_ELS defaults to 0, so add a stub enable function to cover builds with compiler optimisations turned off. The unused mpam_enable() function call will normally be optimised away (because it would never be called), but with -O0 the compiler will leave the symbol in the object file.
