vulkan/wsi: Add basic support for PresentWait2

Browse source 
Add common code for PresentWait2.

Unlike PresentWait, PresentWait2 is exposed by a surface capability.

On Wayland, PresentWait (and PresentWait2) require the presentation-time
extension to be available for a proper implementation, but not all
compositors support this. PresentWait would either have to be exposed
nowhere, or have weird/complicated fallback paths to try to enable it
on systems where presentation-time is unavailable.

Since PresentWait2 has a surface capability, we can simply not expose it
on Wayland when present-time is unavailable instead of always having to
have a less compliant fallback path.

PresentWait2 also explicitly forbids waiting on an ID that hasn't been
queued for presentation, so we don't need to handle that weird case.
