…over to prevent excessive handler rendering (#30709)

Improve the user experience and performance of the `cdk-experimental` column resize feature by adding a `debounceTime` operator to the `headerCellHoveredDistinct` observable. Previously, the hover event triggered the handler immediately, which could result in unwanted handlers showing up when the user quickly moved their cursor over column headers. This change ensures that the handlers only appear if the user pauses (hovers for 300ms) over the column header, preventing handlers from rendering during fast cursor movements.

(cherry picked from commit 6ea0d2d)

Removes the `harness-e2e-cli` integration test, because it's been really flaky and we don't get much out of it. At this point harnesses are mature enough that we're likely not changing the underlying implementation any time soon and there are tons of internal tests to catch any regressions.
