Trace HwKeyHash and Add Errorlog Parser Infrastructure to Secureboot

This commit traces the HwKeyHash to Secureboot-specific error logs.  It also
adds the infrastucture necessary to parse secureboot-specific errorlog user
data sections.  It includes 2 new custom sections: one which is used in this
commit, and another which will be used in a future commit.
