Setting for enabling and disabling VSync

[NogginBops]

Currently GLControl doesn't allow you to set VSync, we should try and expose this setting.

As of writing I don't know the detains on how NativeWindow and the Control is being "kept in sync" so I don't know if some sorcery is needed for this to properly work.

Is there a workaround or anything to use VSync in an OpenTK 4 GLControl?

The OpenTK 3 implementation for VSync sets Context.SwapInterval:

https://github.com/opentk/opentk/blob/3.x/src/OpenTK.GLControl/GLControl.cs#L452

Context.SwapInterval is also a thing in OpenTK 4, could supporting a VSync property in OpenTK 4 be as simple as porting the same logic from OpenTK 3 to OpenTK 4?

It's likely not as simple as in OpenTK 4 we are running a separate window from the WinForms windows. But it could turn out to be that simple, so it's worth a try.

I haven't had the time to look into this issue. If you have any questions about trying to solve the issue yourself I'll try and answer any questions to the best of my knowledge.
