[ToolbarMVC] Move url focus logic to LBMediator

This change moves setUrlFocusChangeInProgress, onUrlFocusChange, and
finishUrlFocusChange to LocationBarMediator, consolidating phone- and
tablet-specific logic as appropriate. Moving these together allows
us to move several pieces of state into LocationBarMediator together,
e.g. mUrlFocusedWithoutAnimations and mUrlFocusChangeListeners.
Unit and instrumentation tests covering the migrated logic are also
included, and some on-focus triggered accessibility logic has been moved
to UrlBarCoordinator.
