Describe the feature you want

In my opinion one should merge the Dialogs from FeedFragment, StatisticsPlaylistFragment, LocalPlaylistFragment, PlaylistFragment; mostly called showStreamItemDialog (showStreamItemDialog) and showStreamDialog (every other)

Also assimilate or even merge the single and long press actions for play / play all / enqueue / popup / background play in LocalPlaylistFragment, PlaylistFragment, VideoDetailFragment in the methods called handleResult (LocalPlaylistFragment, PlaylistFragment), onLongClick/onClick (VideoDetailFragment)

Is your feature request related to a problem? Please describe it

Adding a new action or improving a existing one requires finding every possible place where they are called.

Additional context

Mostly a result of my work on #6872.

How will you/everyone benefit from this feature?

Instead of having to make sure that new actions / changes are applied in every fragment only one obvious file would have to be changed. Searching for where the actions are used would be simplified.

I dont think this actually is a feature request, but is even less of a bug so... Also the button and dialog refactor maybe should be separate issues?
