feat(drtm): retrieve DLME image authentication features
Retrieve DLME image authentication features and report them
back to the DCE preamble. Currently, this value is always set
to 0, as no platform supports DLME authentication.
Additionally, the default schema is always used instead of
the DLME PCR schema since DLME authentication is not currently
supported.
This change primarily upgrades the DRTM parameters version to V2,
aligning with DRTM spec v1.1 [1].
