Provide an API to snapshot views while avoiding animations

[BrianGardnerAtl]

Some views complete rendering after an animation, such as the OutlinedTextField (referenced in #1032). Calling the regular snapshot functions will only grab the first frame which shows the view in an incomplete state. It would be nice to have an API that allowed snapshotting a view after an animation, potentially by specifying a number of frames to skip before taking the snapshot.

I'm using robolectric for some of my tests and it has a nice API for skipping frames until no pending layout/measurements are detected. I think paparazzi would also benefit from something similar.

FWIW here's a more common example: I am migrating my library from BoxWithConstraints to Box but its causing my tests to fail because I'm no longer receiving a layout size in the first frame: saket/swipe@658ffed
