Add initial support for sticky positioning for non-legacy layout (#30686)

* Add initial support for sticky positioning for non-legacy layout

is that CSSOM currently does not return correct values for elements
positioned by sticky nodes. This requires changes to WebRender to work
properly.

* Fix an assertion failure in the legacy layout sticky code
