driconf: Add DRI configuration for exposing VK_KHR_present_wait.

Browse source 
These extensions are flawed and do not support the concept of
per-surface queries. For the time being we cannot guarantee that we are
able to implement it on all surfaces, but the feature is useful enough
to make available as an opt-in feature for the time being, so hide it
behind an driconf until we have a better mechanism in place.
