soc/intel/meteorlake: Add entries to eventLog on invocation of early SOL
This patch records early signs of user activity during CSE firmware synchronization or MRC (re)training events in the event log (ELOG_TYPE_FW_EARLY_SOL).
These can be used to ensure persistence across global reset (e.g. after CSE sync) so that they can be later retrieved in order to build things such as test automation ensuring that we went through the SOL path/display initialized.
BUG=b:279173035 TEST=Verified on google/rex, event shows in eventlog after CSE sync and/or MRC.
Scenario #1: While performing MRC update

Scenario #2: While performing CSE update/downgrade

Scenario #2: While performing both MRC and CSE upgrade
