Subject: [PATCH] Send LockPatternView accessibility announcements before
 callbacks

This allows the pattern's listener to optionally send accessibility
announcements that interrupt the defaults, rather than the view always
interrupting the listener.

Bug: 7256500
Change-Id: Ief2f5cc2fae76a3becc1321d14d46f97b3092215
