Add collection for new CSS features

[Elchi3]

Chrome 135 beta is apparently shipping the following CSS features which we currently don't have tests for. Can we add them?

• ::column selector "it only exists on multi-column containers" (https://chromestatus.com/feature/5192332683771904)
• *progress() functions (https://chromestatus.com/feature/5112558941634560)
• max-area-safe-inset-* env() variables (https://chromestatus.com/feature/6393888941801472)
• ::scroll-button() selector (https://chromestatus.com/feature/5093129273999360)
