Expose flag to report palm detected by firmware to gestures-lib

We currently don't report palms detected by firmware to gestures-lib,
this leads to situations where gesture lib consideres a touch to be
lifted if  its reported as palm by firmware. This can also cause
unintended tap-to-click, and prevent bottom-right click from working as
intended.
