mac/app: use new open url App event to simplify open file event handling

this event has several advantages, it unifies the mpv:// url handling,
the dropping of files on the App icon and opening via finder into one
event, and it also lets us remove the file open workaround.

we had to keep track of opened files via the command line because the
event was also triggered by passed files on the command line, leading
to redundant load events.

the new event doesn't trigger from files passed via the command line
anymore.
