MdePkg/PeCoffLoader: fix handling of ARM MOVW/MOVT instruction relocs
Advance the *FixupData pointer after use in the second relocation pass
for runtime when handling ARM MOVW/MOVT immediate relocations.
Note that using FixupData is somewhat pointless for relocations targeting
instructions rather than data items, since the program cannot typically
modify its own instructions, and the second pass should be performed
unconditionally. But let's just fix it for now.
