Create DisplayWindowPropertiesRepository

The repository will provide per display window properties. These
properties are display specific and window type related.

If for example someone wants to add a window of type TYPE_STATUS_BAR to
an external display, the properties will contain the correct Context and
WindowManager to be able to do so.
