feat(spm): add a measured boot test config

Add a test configuration permitting to measure components loaded by BL2
and in particular secure partitions, to be consumed at later boot stage

In this test configuration the SPMC is Hafnium to which the event log
address is passed at boot time through the SPMC manifest
