Subject: [PATCH] ArmVirtPkg: add FDF rule for self-relocating PrePi

In preparation for making the self-relocating PrePi use the ordinary
BasePeCoffLib routines for relocating the image in place in memory
at start, add a special FDF rule that builds SEC modules as PE32
images with the relocation metadata preserved.
