MdePkg/Uefi ARM: only support native ARM/Thumb images 

The ARM calling convention is fundamentally incompatible with EBC,
and having a cross compatible machine type identical to the native
type does not make a lot of sense either. So restrict the compatible
machine type for ARM to EFI_IMAGE_MACHINE_ARMTHUMB_MIXED, and remove
the cross compatible.
