ArmVirtPkg: KvmtoolRtcFdtClientLib: Set MMIO Memory NX
When setting memory attributes on its MMIO region,
KvmtoolRtcFdtClientLib will clear EFI_MEMORY_XP from
the region if a platform has it set. This MMIO region is
not intended to be executed from, so fix this by explicitly
setting EFI_MEMORY_XP on this region in the lib.
