BeagleBoardPkg: create private PrePi implementation
Clone the PrePi implementation for BeagleBoardPkg, so we can start removing some of the awkward optimizations that we'd rather not keep in reference code. Note that we only clone the unicore ARM flavor, which is all we need for BeagleBoard. In the case of PrePi, it involves libraries included by the SEC startup code that are exposed to DXE core via HOBs containing function pointers, which forces us to keep the primary FV reserved in memory.
