drm/atomic: add connector to atomic context

This patch adds
  - DRM connector object to atomic context.
  - fd property to the drm atomic object as well as a method to read blob type properties.

This allows to ensure that the proper connector is picked up, especially when specifying it
from the commandline, and also allows to make sure we're using the right one when embedding
with interop into an application.
