seat: discrete round away from zero + high res scrolling (#6317)

Browse Source 
* Discrete scrolling round away from zero
e.deltaDiscrete can be multiples of 30 instead of the usual 120 causing
the rounded value to be 0 when too small causing erratic scrolling.

* Send value120 alongside discrete
Fixes sensitivity issues for clients that support value120 axis events
