When navigating fields using the keyboard, it's not possible to reach
most of widgets for selection fields. That is because most of them
consist of one main element containing several other ones, one per
possible selectable value (e.g. buttons). When their focusable element
is computed, the main element is taken, instead of its sub-elements,
which causes the field to be skipped when navigating.
This commit fixes the above, as well as some missing aria attributes and
keyboard events, for the following widgets:
- `priority`
- `state_selection`
- `statusbar`
- `radio`
