ArmVirtPkg: Correct PcdDxeNxMemoryProtectionPolicy comment
Since commit 2997ae387397 ("ArmVirtPkg: make EFI_LOADER_DATA
non-executable") the comment for PcdDxeNxMemoryProtectionPolicy is
incorrect.
* Remove the incorrect part of the description.
* Describe overriding NX protection by passing a pcd parameter on the
build command line.
