Ovmf/Xen: move XenBusDxe to abstract XENIO_PROTOCOL

While Xen on Intel uses a virtual PCI device to communicate the
base address of the grant table, the ARM implementation uses a DT
node, which is fundamentally incompatible with the way XenBusDxe is
implemented, i.e., as a UEFI Driver Model implementation for a PCI
device.
