UI: Move "enforce" setting to "ignore" stream section

Moves the "Enforce streaming service bitrate" option from simple output
mode to the stream section, renames it to "Ignore streaming service
setting recommendations" (inverting it). When trying to check it, it
will now also display a message box warning the user that it's generally
a not-so-good idea.

Also displays recommended settings for the service.
