xen: add guest bundling infrastructure with cross-install class

Add xen-guest-cross-install.bbclass for bundling Xen guest images into
Dom0 host images at build time. Supports per-guest configuration via
varflags (memory, vcpus, vif, kernel extra), custom config files,
external/pre-built guests, and autostart via /etc/xen/auto/ symlinks.

Also add example-xen-guest-bundle recipe as a template, and simplify
xen-guest-image-minimal by removing the old XEN_GUEST_AUTO_BUNDLE
do_deploy mechanism in favor of the new class-based approach.
