LibGfx+Overall: Remove is_null from Point, Rect and Size

Browse source 
Having a `Point`, `Rect` or `Size` claim it's `null` is silly. We have
`Optional<T>` for that. For `Point`, rename `is_null` to `is_zero` to
better reflect what we're testing. For `Rect` and `Size`, `is_null` is
removed outright.

Also, remove `is_empty` from `Point`. Points can't be empty.
