feat(drtm): update DLME data header with actual Event Log size

Browse source 
The definition of `dlme_tpm_log_size` has been revised to represent
the actual Event Log data size instead of the fixed minimum of 64KB.
This change will be reflected in the upcoming DRTM specification
update.

Note: This change requires a corresponding update to the ACS DRTM
app in CI.
