texture sliced UI nodes are sized intrinsically since required components changes #16109
Description

What's wrong
UiImage requires Node which requires ContentSize which means all nodes with a UiImage are sized based on the size of the image.
To use texture slicing you have to add a ImageScaleMode component to a UiImage node. This means that texture slice nodes inherit the intrinsic sizing of UiImage nodes. But texture slicing is a method of resizing an image to fit a node, so it doesn't make sense for the size of the source image to be a constraint on the size of the target node.
