Fix NSSL falsing in all builds

Touch events were getting processed multiple times by the FalsingManager, leading to incorrect falsing and the UI being reset. These fixes ensure each touch gets processed once, and by the correct owner.

This is a followup of I228090b917a25a7d1ac459c10f0a1d98167d435a that removes the flag guarding so that this change applies to all builds.

Flag: NONE
Test: manual; observe falsing logs when swiping on shade
Fixes: 316551193
Change-Id: Ieaecd1272cf297f23dce6f72b52fd4912a1a0a66
