x86/bugs: Add AUTO mitigations for mds/taa/mmio/rfds
Add AUTO mitigations for mds/taa/mmio/rfds to create consistent vulnerability
handling. These AUTO mitigations will be turned into the appropriate default
mitigations in the <vuln>_select_mitigation() functions. Later, these will be
used with the new attack vector controls to help select appropriate
mitigations.
