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.

Log Message:
-----------
ArmVirtPkg/PrePi: use standard PeCoff routines for self-relocation
Instead of having a GCC specific routine to perform self-relocation
based on ELF metadata, use the PE/COFF metadata and the existing
PeCoff library routines. This reduces the amount of bespoke assembler
code that is a burden to maintain, and is not portable across the set
of toolchains we support.
This does require some special care, as we have no control over how
the C code references global symbols, so we need to emit these
references from the calling assembler code. Otherwise, they may be
emitted as absolute references, in which case they need to be fixed
up themselves, leading to a circular dependency.

ArmVirtPkg: remove unused files
We no longer use ELF PIE executables to implement the self-relocating
PrePi so drop the custom linker script and visibility override header
file.
