layout: Round clientTop, etc queries to pixels properly (#31187)

* layout: Round getClientRect queries to pixels properly

Instead of just flooring all pixels in getClientRect queries, we should
round the rectangle.

* Fix scrollWidth/scrollHeight too, and tests

* Tests passing

* Test expectation for legacy layout
