Add Secure Version Lockin BIOS Attribute

This commit introduces a new BIOS attribute for secure version lockin
support. When the attribute is set, HB will accept the new incoming
secure version as the default min secure version on the system. When
the lockin is disabled, the min secure version will stay the same
despite code updates.
