Store VelocityTracker strategy in ViewConfiguration

To avoid excessive binder calls from the UI thread while processing
input events, let's store the VelocityTracker strategy in
ViewConfiguration.

This also solves the problem of some apps not being able to read device
config - now, this config will be read by system_server and will be
available to anyone.
