Add a 5 second timeout to launch animation touch blocking

This is a workaround for b/288507023, which is caused by launch
animations hanging. It does not address the cause of the animation
not completing, but it will allow users to resume interacting with
their device after 5 seconds.

Test: added unit test
Test: simulated the bug with a temporary change and verified manually
