clip_check_recursive fix

[ickshonpe]

Objective

clip_check_recursive stops at the first unclipped ancestor when it should progress all the way to the root element unless the given point is clipped.

Fixes #24680

Solution

Early return if the entity is a root.
Then check if the point is clipped and if so return false.
Otherwise recurse to next ancestor.

Testing

cargo run --example feathers_gallery --features="bevy_feathers"

The scrolling list should no long block the x text input when scrolled all the way down.
