  [iOS] <select> UI is not updated if options are changed
https://bugs.webkit.org/show_bug.cgi?id=235911
rdar://88292987

Reviewed by Wenson Hsieh.

On iOS, <select> UI is driven by `FocusedElementInformation`, which is sent to
the UI process each time a control is focused. However, if the control is already
focused, there are currently no mechanisms for changes to element information to
be sent to the UI process. Consequently, any changes to options while a <select>
element is focused are not reflected in the UI process.

Fix by adding a general mechanism to update `FocusedElementInformation` for
controls that are already focused, and adopt it for <select> option changes.

In the future, this mechanism could be used for updates to other control types.
