glvideomixer: swap control binding proxy
...
The ref_object and object parameters were the wrong way around.
For the typical use case where an application is setting a
GstControlBinding on the returned ghost pad:
1. our control binding would be removed when the new one was set
2. sync_values calls were not being forwarded from the internal
pad to the ghost pad.
If an application attempts to perform other control binding
operations (get_* family of functions) on the internal pad, they
will also be forwarded to the ghost pad where a possible
GstControlBinding will provide the necessary values.

glvideomixer: Add GstControlBinding proxy
...
This is used to proxy GstControlBinding to the pad on the
parent object. This avoid having to sync the values in the proxy pad,
this is too early if you have a queue between the pad and the actual
aggregation operation.
