x86/gen-cpuid: Distinguish default vs max in feature annotations
The toolstack logic can now correctly distinguish a clean boot from a
migrate/restore.
Allow lowercase a/s/h to be used to annotate a non-default feature.
Due to the emulator work prepared earlier in 4.14, this now allows VMs to
explicity opt in to the TSXLDTRK, MOVDIR{I,64B} and SERIALIZE instructions via
their xl.cfg file, rather than getting them as a matter of default.
