Chat popup (#3098)

* add pop out chat button

* add button to close chat popup

* chat is hidden on main interface when a popup chat is open

* NameChangeEvent renames clients with the given id

if you have two or more owncast windows (or pop-out chats) open, changing your
name in 1 client is reflected in all clients.

* replace isChatVisible booleans with chatState enum

* update stories to use ChatState

* fix build tests
