Summary [css-anchor-position-1] scrollbars are not handled correctly

We're not doing the math for scrollbars correctly, which is causing us to fail https://wpt.live/css/css-anchor-position/anchor-position-borders-002.html A variant of the test using position-area fails less badly, only failing in cases with scrollbars on the left side. (It passes in other writing modes.)

Now that we've integrated PositionedLayoutConstraints into anchor() handling, we're just failing due to the RTL scrollbars.
