Fix qemuboot-xen-dtb to properly add dom0 bootargs by using a parameter
instead of directly using the QB_XEN_DOM0_BOOTARGS inside the function.
When not done, the variable is empty and dom0 bootargs are wrong in the
device tree.
Use QB_MACHINE to generate a device tree with qemu instead of always
using the armv8 machine. This will allow this class to be used for other
machines later.

The qemuboot device tree generation task in qemuboot-xen-dtb.bbclass
requires the QB_SYSTEM_NAME variable to be set to identify the Qemu
binary to use. Skip the task if it is not set.

The Xen hypervisor built for Arm 64-bit targets can be launched with
runqemu by providing a Device Tree binary and configuration for Qemu,
which enables interactive testing of Xen images.
Add qemuboot-xen-dtb.bbclass to add a new bitbake task for generating
the dtb file by using lopper on a device tree produced by Qemu.
Add qemuboot-xen-defaults.bbclass to supply working default parameters
for the qemuarm64 machine and general support for qemuboot for Xen,
and adjust the defaults as needed to boot successfully in testing.
