We have a lot of ISimpleDOM code which only works for LocalAccessible. Because all web content uses RemoteAccessible now, practically, the only usable ISimpleDOM functionality is that which works for RemoteAccessible. Therefore, remove all code that only works for LocalAccessible. Differential Revision: https://phabricator.services.mozilla.com/D241805
