AmpereAltraPkg: Support rebootless in-band firmware update

This implements the in-band firmware update without rebooting via UEFI runtime services. The FW update service is hooked into the UEFI variable with the variable GUID gAmpereFWUpgradeGuid. Users in the operating system can download the update image to the service by setting continuously a chunk of the image via the variable. And, poll the status by getting the same variable. There are four type of the firmware image supported: - UpgradeSCPRequest: Upgrade SCP. - UpgradeATFUEFIRequest: Upgrade full FW including ATF, board config and UEFI. - UpgradeCFGUEFIRequest: Upgrade only board config and UEFI. - UpgradeUEFIRequest: Upgrade only UEFI.
