[TTS] Fix reparenting and add Test case.
Updates ContextualSearchTabHelper to handle reparenting correctly,
and improve usage of the mTab member to make that usage more explicit.
Adds a new TabObserver method onActivityAttachmentChanged to notify Tabs
when they've been attached or detached from an Activity.
Also refactor mulitwindow test utility methods into a separate utility
class: MultiWindowTestUtils.java, based mostly on static functions
from MultiWindowUtilsTest.java.
