V2: Use resolution to round sensor event values

Add method to utilize a sensor's specified resolution value to ensure
data isn't provided that is more fine-grained than expected. This
helps mitigate sensor calibration fingerprinting attacks.

Bug: 147725937
Test: Verify accel sensor data isn't more fine grained than its
specified resolution
Test: Verify that the max range specified is a multiple of the
resolution
