layout_2020: Stop throwing away hoisted boxes in nested absolutes
We were previously throwing away some boxes hoisted to containing blocks
for all descendants when they were contained by absolutes. This prevents
panics in existing web platform tests that would otherwise be triggered
by the addition of the `unreachable!` statement.

layout_2020: Use ArcRefCell to track hoisted fragments
This avoids the use of lookup tables for containing blocks when
constructing the stacking context tree.
This seems to catch some laid-out hoisted fragments that were otherwise
dropped in the previous design. The changes cause one new test to pass
and one to fail. Visual examination of the failing tests reveals that
it's a progression (list markers are appearing when they were previously
not rendered).

Avoid a panic when closing webgl pages using VAOs

- [x] These changes do not require tests because GC behaviour at shutdown is nondeterministic and difficult to test

Update webxr and webxr-api.
This allows us to re-enter immersive mode on HoloLens, and also allows us to test immersive-ar scenes in the glwindow backend.
layout_2020: Use ArcRefCell in the fragment tree
This will allow mutability which is useful for things like animations.

Set user interactions for tasks
fix#26026
I need help here. Retrieving the interaction flag from the promise handle crashes.
```rust
let interaction = GetPromiseUserInputEventHandlingState(promise);
```
