ozone: Use DeviceCapabilities in TabletEventConverterEvdev unittest

This change enhances the tests for TabletEventConverterEvdev to support
different device characteristics by loading the device properties from a
DeviceCapabilities structure. Unfortunately I no longer have the device
for which the original test was written from so this change switches the
data used over to a different Wacom Tablet.

This work is in preparation for tests for on-screen active stylus
devices which will have different device properties.

The new data highlighted a bug in TabletEventConverterEvdev where we
were failing to zero the initial absolute position.

TEST=events_unittests passes.
