glupload: always add texture-target field to GL caps 1. Various elements/base classes only perform a subset check on accept-caps 2. Some GL elements have texture-target in their pad template 3. When checking subsets, only the caps to check are allowed to contain extra fields. If the 'template' caps have extra fields, the subset fails. Thus without texture-target on the caps, various accept-caps implementations were failing. Also, add some convenience functions for setting and retrieving texture targets to/from GValue. https://bugzilla.gnome.org/show_bug.cgi?id=759860
