ash: Visual and accessibility feedback for in-session fingerprint auth

If fingerprint scan failed, provide visual feedback (animation and
prompt text change) to the user. Also add accessibility feedback:
ChromeVox would play an alert sound and say the fingerprint auth result.

These are the same effects as lock screen except that the prompt text
strings mention "authenticate" instead of "unlock".

Bug: b:156258540, b:144861739
Test: Tested with ChromeVox.
