renderer: disable explicit if aquamarine output doesn't support it (#9396) (#9398)

The explicit settings ignore the aquamarine output.supportsExplicit
attribute, which creates glitches on drivers not supporting explicit
sync (example: freedreno).

If the output has been set as not supporting explicit, disable the
explicit settings.
