fix(#3672): WHCM/forced-colors support for column resizer

[majornista]

Relates to #3672 , #3368 and #3529

Fix to support @media (forced-colors: active), aka Windows High Contrast Mode, with the Column Resizer, Column Resize Indicator and Nubbin. It doesn’t include comprehensive fixes for other WHCM issues in Table, but at least this feature will not seem broken.

Open Table Column Resize examples with Windows High Contrast Mode/forced-colors turned on.
