LibWeb: Make HTML{Button,Select,TextArea}Element focusable

Browse source 
From the HTML spec:

    Modulo platform conventions, it is suggested that the following
    elements should be considered as focusable areas and be sequentially
    focusable:

      ...
    - button elements
    - select elements
    - textarea elements
      ...

Also add a spec link to the existing HTMLAnchorElement::is_focusable().

Note that this still doesn't allow triggering keyboard-focused buttons,
checkboxes, or radio buttons - we don't seem to run the expected
activation behavior for any of them.
