[view-transitions] Mispositioned snapshots on
https://codepen.io/bramus/full/mdowgYX
https://bugs.webkit.org/show_bug.cgi?id=272185
rdar://125931829
Reviewed by Simon Fraser.
We were previously unconditionally substracting the scroll position from the
transform when positioning the snapshots.
This is incorrect in some cases, like when the element is fixed positioned.
This makes use of the existing TransformState/mapLocalToContainer code to
correctly account for position:fixed when accumulating
transforms through ancestors.
It also adds support for flattening the 'tracked' transform when crossing 3d
rendering context boundaries, by setting the 3rd row
and column of the TransformationMatrix to 0.
