Summary: Pull Request resolved: facebook#46189 A lot of the style decorators we have (filters, box shadows, borders, etc) use a separate sub-CALayer to accomplish what they want. This becomes an issue if we are clipping the content to the bounds and if these decorators extend beyond the bounds of the view as they are typically unaffected by this clipping. The main things here are `box-shadow` and `outline`. However, this implementation will let us fix some issues w.r.t content rendering under borders. See later diffs for that. To fix this, if needed, we insert a `_containerView` to contain all of our subviews, and actually apply the clipping to. If this exists, our UIView will only have one subview, this one. But it may have multiple sublayers. NOTE: This diff does not actually redirect the clipping. It just inserts the subview to test if this breaks anything in and of itself.
