fsp1_1: move relocation algorithm to commonlib

In order to support FSP 1.1 relocation within cbfstool
the relocation code needs to be moved into commonlib.
To that end, move it. The FSP 1.1 relocation code binds
to edk2 UEFI 2.4 types unconditionally which is separate
from the FSP's version binding.

BRANCH=None
TEST=Built and booted glados.
