Support for SPDM events with the TPM eventlog

[chubtub]

The TCG Platform Firmware Profile v1.06 introduced several new event types in support of DMTF Security Protocol and Data Model (SPDM). Support for parsing the new Event Types was previously implemented in the ACA and the tcg_eventLog_tool over previous issues: #747, #757 , #784 , #747, #793, #804, and #820.

This Issue will will add a new policy for the ACA to process SPDM event content when present in the TCG Event Log. SPDM event content is expected to contain component certificate and component measurement data collected by the devices Firmware. While the ACA will be limited in terms of what it can validate about the SPDM event content collected by the Firmware in the TCG Event Log, the data is is expected to provide useful set of evidence used for establishing the devices trust.
