Introduce the videocolorscale element

Browse source 
Now that videoconvert and videoscale's are both based on
GstVideoConverter and are using the exact same code, it makes much more
sense to have one element doing the two operation, and it can be
more efficient in some cases (one single path for both operations).

This removes the `videoscale` and `videoconvert` plugins but keeps the element
but makes them also do both operations (adding some APIs to each element).

There is a small change in API for the `videoscale:dither` property which
was previously a totally unused boolean, it is now an enum and is used.

/**
* SECTION:element-videoscale
* @title: videoscale
* @see_also: videorate, videoconvert
*
* This element resizes video frames. By default the element will try to
* negotiate to the same size on the source and sinkpad so that no scaling
* is needed. It is therefore safe to insert this element in a pipeline to
* get more robust behaviour without any cost if no scaling is needed.
*
* This element supports a wide range of color spaces including various YUV and
* RGB formats and is therefore generally able to operate anywhere in a
* pipeline.
*
* ## Example pipelines
* |[
* gst-launch-1.0 -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoconvert ! videoscale ! autovideosink
* ]|
* Decode an Ogg/Theora and display the video. If the video sink chosen
* cannot perform scaling, the video scaling will be performed by videoscale
* when you resize the video window.
* To create the test Ogg/Theora file refer to the documentation of theoraenc.
* |[
* gst-launch-1.0 -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoconvert ! videoscale ! video/x-raw,width=100 ! autovideosink
* ]|
* Decode an Ogg/Theora and display the video with a width of 100.
