bitbake: toaster: add modal to select custom image for editing

Add functionality to the placeholder button on the build dashboard
to open a modal dialog displaying editable custom images, in cases
where multiple custom images were built by the build. Where there
is only one editable custom image, go direct to its edit page.

The images shown in the modal are custom recipes for the project
which were built during the build shown in the dashboard.

This also affects the new custom image dialog, as that also has
to show custom image recipes as well as image recipes built during
the build. Modify the API on the Build object to support both.

Also modify and rename the queryset_to_list template filter so that
it can deal with lists as well as querysets, as the new custom image
modal has to show a list of image recipes which is an amalgam of two
querysets.
