tdf#149969 slideshow: handle loop from the animation of a media shape

Impress supported video looping on media shapes, while PowerPoint
supports this as part of the animation tree for the slide. To be more
specific, it seems in case there is play command, then it looks up if
there is a media node of the timing tree that has the current shape as
its target, and checks if the looping is enabled for this shape in this
media node.

The PPTX import already creates an (audio) node for the media shape and
we have UNO API to set/get a RepatCount attribute on this.

Rather than tweaking the PPTX import to create a different doc model,
just extend the rendering so in case the shape doesn't enable looping we
can also notice that an animation requested looping.

The PPTX export doesn't write a media node for videos at the moment, so
that still needs work.
