Update select shadow tree when contents of selected option change (#36958)

Browse source 
The label that is displayed inside a `<select>` element is that of the
selected option, or it's text contents if the option does not have a
label. Therefore, we need to update the `<select>` shadow tree when the
contents of the selected option change.

Testing: Covered by existing web platform tests
