Clean up multiple RenderedPosition::absoluteRect definitions and correct LayoutUnit usage

[Levi Weintraub]

There are currently 3 definitions of RenderedPosition::absoluteRect where only one is needed. It also currently returns a LayoutRect despite being in absolute coordinates, which should be integers.

For people watching at home, the pixelSnappedIntRect confused me a lot and I pinged leviw@ about that. Currently we want to snap our rectangles before calling localToAbsoluteQuad to be consistent across all the painting code.

We may lose some precision by doing so (if we have a transform that is not pixel aligned for example), but coherency is better for now. We may relax this requirement later.
