Add touch device fixture and update test payload

Add a 'test_touch' device to the test devices (features: lcd + touch, touch.platform: gt911) and modify the touch_area test to set deviceModel: 'test_touch' in the payload. The profile.touch flag was removed so the test relies on the device model to indicate touch capability when generating YAML.
