Fix race condition where wrong caps were sometimes received before
the last gap internal clip by setting explicit framerate in video
caps and adjusting test timing accordingly.
The test now uses framerate=1/1 with single buffer expectations
instead of relying on default 30fps timing that created timing
races with the internal gap clip processing.

The responsibility to change the framerate to the one
requested on the VideoTrack should always be the last time effect in it.
This introduces a new `capsfilter` at the end of video effect that
will be in passthrough most of the time.

This allows user to be in control of when scaling happens in the pipeline.
It can be plugged as an effect and scaling will be forced to happen in
the effect instead of in the compositor.
Without this, it would not be possible for users to, for example,
crop a video source before scaling to the target source size.
