Add an accessibility mode for editable text fields only.
This refactors the triggering of accessibility mode from a boolean state and
command-line flag to an AccessibilityMode enum that's passed directly
when a new RenderView is created, which is also more readable and avoids the
extra command-line flag.
Adds a new mode that only syncs editable text nodes, and enables this on
Windows 8 so that we can support showing the virtual keyboard when an
editable text field gets focus.
