ges: Add support for sources reverse playback It introduces a `reverse` property at the `nlesource` level which will basically reverse playback of the clip. We guarantee that outside that clip, the data flow looks like it was playing forward as we add an 'identity' element with `single-segment=true`. This start making use of the newly introduced concept of `CHILD_PROP_FLAG_SET_ON_ALL_INSTANCES` as it is natural that doing `source_clip.set_child_property("reverse", True)` will make the whole clip go reverse, meaning that all the GESSource children properties will be set. To set an individual source "reverse" child property as the desired effect.
