[PATCH v2] selftests: hid: tests: test_wacom_generic: add tests for display devices and opaque devices

[Alex Tran <alex.t.tran@gmail.com>]

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.

- 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
