meta-agl-bsp: Define Xen recipe

Provide Xen support for Arm64 boards, tested with the R-Car M3 ulcb
board. Xen v4.13.0 stable version is compiled.

A new binary is deployed, named "xen-${MACHINE}.uImage" that can be loaded
and run by U-Boot.

v2: rework to split u-boot mkimage part a separate recipe so we can
    keep the diff of the xen recipe at a minimum.

Bug-AGL: SPEC-2912
