Move link sharing into share with user-dropdown

[MariusBluem]

Unify all sharing options into one single menu.

• Would give the possibility to have multiple link shares with different permissions and possibilities to revoke
• To not hide this option too much, we would need the default expanded menu from Show 3 latest contacts/circles or groups #5335

It looks nice, the only problem I see is that it might be hard to discover the share link feature this way. Because you need to click in the input field and then it will magically appear (the way auto-completion works today you would even have to start typing some random stuff to trigger it, but this might be solvable)
