Ensure that onBoundsDefined width and height is >= 0

Summary:
It's theoretically possible that in onBoundsDefined case we would end up using a negative width/height. It could happen when `layoutResult.width` or `layoutResult.height` is less than the sum of paddings and borders.

This diff ensures that the computed content width and height will always be >= 0.
