  Cleanup / micro-optimize RenderLayers accumulateOffsetTowardsAncestor helper
https://bugs.webkit.org/show_bug.cgi?id=245395

Reviewed by Rob Buis.

Avoid unnecessary LayoutPoint -> LayoutSize conversions (e.g. when applying
scroll offset, or when moving 'location' by the result of 'localToAbsolute').

Use auto in a few more places, where it helps readability.

Covered by existing tests.
