MdeModulePkg/DxeCore: Allow relocation of images with large address
Add PCD to control if modules with start addresses in PE/COFF > 0x100000
attempt to load at specified address.
If a module has an address in this range and there is untested memory
DxeCore will attempt to promote all memory to tested which bypasses any
memory testing that would occur later in boot.
There are several existing AARCH64 option roms that have base addresses
of 0x180000000.
