Verify Wacom devices set INPUT_PROP_DIRECT on display devices and INPUT_PROP_POINTER on opaque devices. Verify INPUT_PROP_POINTER is not set on display devices and INPUT_PROP_DIRECT is not set on opaque devices.

Moved test_prop_pointer into TestOpaqueTablet. Created a DirectTabletTest mixin class for test_prop_direct that can be inherited by display tablet test classes.Used DirectTabletTest for TestDTH2452Tablet case.

Changes in v3:
- add assertion for prop tests where opposite is not set

Changes in v2:
- Removed the tests from the BaseTest class
- Removed disabling tests for certain subclasses
- Moved test_prop_pointer under TestOpaqueTablet
- Created DirectTabletTest mixin class
- Moved test_prop_direct under TestDTH2452Tablet
