Fix: display: inline-grid considered an atomic inline (#36298)

This change ensures that `display: inline-grid` is considered an atomic
inline

- Add `is_atomic_inline_level()` logic to `box_fragment.rs` to improve
accuracy.
- Update `stacking_context.rs` to use the new `is_atomic_inline_level()`
method instead of the one from stylo.
- Update `repeat-auto-fill-005.html` test expectation.
- Remove .ini expectations for tests that are no longer failing.

Testing: covered by WPT
Fixes:  #35310
