Thibault Saunier d268c193ad videoaggregator: Guarantee that the output format is supported 
In the case `videoaggregator` is set as allowing format conversions,
and as we convert only on the sinkpads, we should ensure that the
chosen format is usable by the subclass. This in turns implies
that the format is usable on the srcpad.

When doing conversion *any* format can be used on the sinkpads, and this
is the only way that we can avoid race conditions during renegotiations
so we can not change that fact, we just need to ensure that the chosen
intermediary format is usable, which was not actually ensured before
that patch.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/834
