Subject: [PATCH v1] selftests: hid: tests: test_wacom_generic: add base test for display devices and opaque devices

Verify Wacom devices set INPUT_PROP_DIRECT appropriately on display devices
and INPUT_PROP_POINTER appropriately on opaque devices. Tests are defined
in the base class and disabled for inapplicable device types.
