[feat]: Use the new XS IconButton to clear the Searchbar

[lucasboilly]

A clear and concise description of what the feature is

Replace the current clear cross icon with the new XS variant of the IconButton.

Why should this feature be included?

• It increases the click area and makes it more accessible.
• It adds hover and clicked states directly inherited from IconButton.

Please provide an example for how this would work

It's supposed to look like this. Please make sure that the IconButton is vertically centered and 4px away from the right edge of the Searchbar.
