bitbake: toaster: Add CustomImageRecipe model

This model lists custom image recipes for the project.
It is populated when new custom image is created.
It holds reference to the base recipe and list of packages
included into custom image.

For CustomImageRecipes the packages will be copied in and
therefore not associated with a build so Remove the requirement
for the package to have a Build.
