mac: activate logging when started from the bundle

this creates a default log for the last mpv run when started from the
bundle. that way one can get a log of what happened even after an issue
occurred. also add a menu entry under Help to show the current log, but
only when the bundle is used.

Fixes mpv-player#7396
