macosx: Use floating window level for effects and other panels

All black-syle panels should get the floating window level.
This is normal behaviour of panels and has the positive side effect
that the panel also stays in front while vout window reconfigurations.

This level is also used for the preferences window, as this is sort
of a modal window which needs to be closed (in order to get settings
saved).

macosx: video effects: only set video splitters when needed

Avoids setting this variable multiple times, as each time vout
restart is requested. Also avoids unnecessary vout restarts at
start and when changing profiles.
