EmbeddedPkg: introduce GPIO PPI
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.
