AMD: Isolate AGESA and PI build environments for southbridge

To backport features introduced with recent Chromebooks and/or Intel
boards in general, heavy work on the AMD AGESA platform infrastructure
is required. With the AGESA PI available in binary form only, community
members have little means to verify, debug and develop for the said
platforms.

Thus it makes sense to fork the existing agesawrapper interfaces, to give
AMD PI platforms a clean and independent sandbox. New directory layout
reflects the separation already taken place under 3rdparty/ and vendorcode/.
