player/gir: Trust annotation nullability and remove all overrides
Fixes #300 (closed)
Draft MR to get insight in the changes made when trusting gir
files for the player
. This diff hopefully sheds some weight when gst-plugins-bad!2197 (merged) lands, but we'll have to see how to backport that to 18.x
first, if at all.
