[css-anchor-position-1] Adjust anchor()/anchor-size() for viewport and CSS
zoom
rdar://146806814
https://bugs.webkit.org/show_bug.cgi?id=289578
Reviewed by Antti Koivisto.
The value returned by anchor()/anchor-size() is calculated at 1x viewport zoom,
which is wrong if either:
* the viewport is zoomed using Ctrl+/Ctrl-, or
* CSS zoom property is used.
This patch fixes this by adjusting the returned value by the zoom factor.

Added.

- Added test for anchor() + viewport zoom. This test can't be added to WPT,
as WPT does not support changing viewport zoom factor.
