ArmVirtPkg/ArmVirt.dsc.inc: AARCH64: enable DXE image protection feature 

Enable the new DXE image protection for all image, i.e., FV images but
also external images that originate from disk or the network, such as
OS loaders.

This complements work that is underway on the arm64/Linux kernel side,
to emit the OS loader with 4 KB section alignment, and a suitable split
between code and data.
