BeagleBoardPkg: fold configuration header into FD build

BeagleBoardPkg: fold configuration header into FD build

Since the configuration header never changes unless the board parameters
in ConfigurationHeader.dat are updated, we can take a snapshot of the
binary and add it to the FDF definition. This way, it will get emitted
by the EDK2 build system instead of having to use a separate
post-processing tool to add it to the flash image.
