firmware: Add 'templateFormat' XML attribute and plumb it in

Currently the qemu firmware code weirdly depends on the 'format' field of the nvram image itself to do the auto-selection process as well as then uses it to declare the actual type to qemu. As it's not technically required that the template and the on disk image share the type introduce a 'templateFormat' field which will split off from the shared purpose of the type and will be used for the selection and instantiation process, while 'format' will be left for the actual type of the on disk image. This patch introduces the field, adds XML infrastructure as well as plumbs it to the firmware bits.
