xen, raspberry pi: add dynamic-layer for Xen configuration for Rpi4

A Xen-specific u-boot script is needed for launching Xen, and the GIC
(interrupt controller) needs to be enabled.

Since this is both Xen-specific and Raspberry Pi-specific, use a
dynamic layer to conditionally enable the recipes when both
meta-virtualization and meta-raspberrypi are in use together.
