[PATCH 16/45] MdeModulePkg/RecoveryModuleLoadPei: Add RecoveryModuleLoadPei.

[Jiewen Yao <jiewen.yao@intel.com>]

RecoveryModuleLoadPei supports recovery system BIOS via UEFI FMP capsule.

RecoveryModuleLoadPei produces EFI_PEI_RECOVERY_MODULE_PPI. It is invoked
by DxeIpl in recovery boot mode.

LoadRecoveryCapsule() will scan all possible
gEfiPeiDeviceRecoveryModulePpiGuid and get EDKII system FMP capsule there.

LoadRecoveryCapsule() will perform the FMP authentication and version
check. If and only if the FMP authentication passes, and EDKII system FMP
capsule version is equal to the current BIOS Version, the recovery will
be performed. Or this capsule image is discard.
