Sebastian Dröge ff21fe1d25 playbin2, playsink, subtitleoverlay: Set subtitle encoding properly
For this add subtitle encoding properties to playsink and subtitleoverlay
and update the values in the containing elements.

Also update the font description in textoverlay or the used renderer
element if it is changed during playback.

Fixes bug #610310.
