ArmVExpressPkg: add support for embedding DTBs for AArch64 variants 

If DTB_DIR=<path> is set during the build, incorporate DTBs from
that path for all AArch64 FVP platform variants so that they can
be loaded straight from the firmware image instead of from a file
system. This relieves a user of having to keep a DTB file with the
right name in the working directory of the model.
