This name isn't entirely accurate because it generates presets and fetches the current size. I don't love either of these names, but they would be more correct: `getSizeAndGeneratePresets`, or `generatePresetsAndGetSize`?

As we discussed, can this be moved into CreateMediaSourceForCaptureDeviceWithConstraints so we don't need to make two calls to the UI process to become ready?

Can this be removed completely?

Right, let's add it to CreateMediaSourceForCaptureDeviceWithConstraints.

Actually, I need to implement it for clone-then-increase-resolution-or-frameRate cases.
I removed on the other hand the applyConstraintsFailed/Succeeded since they are no longer needed for video.
