LibWeb: Keep select button text in sync with the selected option

Browse Source 
Previously, the select button's text was only refreshed inside the
two non-trivial branches of the selectedness setting algorithm.
Paths that left the select with exactly one selected option hit a
no-op branch and skipped the refresh.

Fix this by implementing the "clone selected option into select
button" algorithm and invoking it whenever the set of selected options
may have changed.
