Refine adjustIsVisibleToUser

A11yInteractionController would adjust A11yNodeInfo's visible when it
is outside of interactive region. Therefore, the top row characters
in pop-up of IME additional characters may be invisible to users. It
causes a11y services can't select these A11yNodeInfo.

Check if window type of ViewRootImpl should be bypassed adjustment.
