Allow some cross activity touches

Resolve app compatibility issues caused by ActivityRecordInputSink
agressivly blocking all touches. This change makes
ActivityRecordInputSink more conservable and it now only blocks touches
if the touches would otherwise:
1. Cross a task boundry
2. Go to an activity with a different uid AND that activity hasn't
   explicilty launched an activity with the same uid as this activity
