[facebook] extract better titles (fixes #14156)

Browse Source 
This now tries to find the primary title, which is displayed in bold
above the previously extracted full text. This is the title which is
also displayed - if given by the uploader - to the top left when
displaying a video fullscreen.

For videos posted to groups, the extractor still doesn't use the
given comment text as a title, and now extracts e.g. "[group name]
Public Group" instead of "[group name] has 481 members", which may
or may not be better.
