MdeModulePkg ErstFmpDxe: Create ESRT in ReadyToBoot event
Current code just creates ESRT entry in FMP notification and installs ESRT configuration table in ReadyToBoot event. The LastAttemptVersion and LastAttemptStatus in ESRT will be out of date after system continues to boot without reset after capsule update (reset is not required or capsule update is failed). This patches updates the code to create ESRT based on all FMP instances in ReadyToBoot event.
