Renamed constellation::Frame to constellation::BrowsingContext
<!-- Please describe your changes on the following line: -->
Now that script has `WindowProxy` rather than `BrowsingContext` objects, we can rename `Frame` in the constellation to `BrowsingContext`. In particular, this means that `FrameId`s are now `BrowsingContextid`s, which better captures their purpose (and they are used in a lot of places, not just the constellation).

Don't optimize display list for projective transforms
There are situations where elements are transformed from outside the
display list. With projective transforms it's currently difficult to
detect these. In those cases we just don't optimize the display list,
so that they will always be shown.
Fixes#13822.

Revert "Replace intrinsics::abort with process::abort"
This reverts #16680. Calling `process::abort` from the crash handler causes the crash handler to be invoked again recursively.

Properly handle scroll offsets in hit testing
Scroll roots are no longer nested containers holding items, so instead
we need to track the offsets of each, carefully handling fixed position
items and stacking contexts that create new reference frames.
Additionally, we remove the complexity of the pre-computed page scroll
offset, instead opting to send script scrolls to the layout task in
order to more quickly have a ScrollState there that matches the
script's idea of the scroll world.
Fixes#16405.
