Subject: [PATCH] Add EmojiPageKeyboardAccessibilityDelegate

Because EmojiPageKeyboardView doesn't use PointerTracker to handle
MotionEvent, a dedicated accessibility delegate is needed. Then the
recent tab can be updated even with accessibility mode on.

Bug: 15582599
Change-Id: I63d75b9aca21ec44f1f77d2eaaf2ba7813992183
