Implement ResetSystemLib's EnterS3WithImmediateWake() routine using a jump back to the PEI entry point with interrupts and MMU+caches disabled. This is only possible at boot time, when we are sure that the current CPU is the only one up and running. Also, it depends on the platform whether the PEI code is preserved in memory (it may be copied to DRAM rather than execute in place), so also add a feature PCD to selectively enable this feature.
