SystemUI: modify AOSP RU translation

Updated a string to say "Cast screen" instead of older "Wireless display"

Change-Id: I10558e36c2ee9f0e53f0de382425a3aceb52cab1
inputdevices: update from aosp (master)

Change-Id: If5fb11c354ea0144cdae1434de4c536302dda5b3
base: remove extra checks

p and p.applicationInfo are always != null (they are checked previously), so below checks
are unnecessaries
