vulkan: Provide a flag in the submit for needing implicit sync for WSI, use in turnip

Emma Anholt requested to merge anholt/mesa:tu-implicit-sync into main

The core can generate appropriate waits for WSI implicit sync on kernel 6.0+, but the drivers weren't getting any flag indicating that they don't need to do their own implicit sync work any more.

Improves turnip+angle asphalt_9 performance by 3.55256% +/- 0.622499% (n=5).
