Verify Wacom devices set INPUT_PROP_DIRECT on display devices and INPUT_PROP_POINTER 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.

Let me CC Benjamin and Wacom folks to take a look here as well.

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
