[omni] Make LPH duration and touch slop dynamically configured.

The override duration and slop multiplier can be set from Launcher. Pass this
value from launcher to sysui through SystemUiProxy.
The logic for touch slop follows NavHandleLongPressInputConsumer (https://source.corp.google.com/h/googleplex-android/platform/superproject/main/+/main:packages/apps/Launcher3/quickstep/src/com/android/quickstep/inputconsumers/NavHandleLongPressInputConsumer.java;l=116).
