[PATCH v2 31/31] OvmfPkg/XenOvmf: use RealTimeClockRuntimeDxe from EmbeddedPkg

["Anthony PERARD" <anthony.perard@citrix.com>]

A Xen PVH guest doesn't have a RTC that OVMF would expect, so
PcatRealTimeClockRuntimeDxe fails to initialize and prevent the firmware
from finish to boot. To prevent that, we will use the
XenRealTimeClockLib from ArmVirtPkg which simply always return the same
time. This will work on both Xen PVH and HVM guests.
