wizard: allow the creation of aarch64 images

This commit extends the supported architectures to aarch64. In the image
output step (the first one of the wizard) the user is now faced with a
new select choices to pickup the architecture they want to build.

Now the set of compatible targets to build is dynamically loaded from
the backend and the UX changes what's accessible on the fly depending on
what's the user has been selected.
