Update autofill keyboard accessory a11y.

The bug is about focus after autofill, but the keyboard accessory
has similar default Home focus in other places, this CL tries to
address the whole screen reader UX as these places are also related
in code.

Key points of changes:
1. Put a11y focus on the list of password options (first item)
   upon opening (was on the Home button)
1.1. Announcement of opened password options (Showing saved passwords
     and password options) removed, the description of the trigger
     button is changed to compensate it.
2. Put a11y focus on the active DOM element after closing Password
   options list and showing keyboard (was on the Home button)
3. Put a11y focus on the active DOM element after autofilling (was on
   the Home button)

Please find these changes in the same order performed in videos:
