Introduce a PPI counterpart of the existing 'embedded GPIO' protocol, so we can manipulate GPIOs from PEI modules. This allows things like setting the boot mode based on a DIP switch setting. Note that the naming is slightly awkward, as there is nothing 'embedded' about a GPIO, but given that the DXE protocol already resides here and has the 'embedded' prefix, it makes sense to retain uniformity.
