SecurityPkg: TcgDxe,Tcg2Dxe,TrEEDxe: New PCD for TCG event log and TCG2 final event log area 

TCG event log and TCG2 final event log area length can be configurable to meet platform event log
requirement.
PcdTcgLogAreaMinLen    : 0x10000  based on minimum requirement in TCG ACPI Spec 00.37
PcdTcg2FinalLogAreaLen : 0x8000   based on experience value
