camera vts: Skip regular vts tests for secure only cameras.

Bug: 156749607

Test: fake mark a camera id as a secure only, see that it doesn't get
      tested unless a test calls getCameraDeviceNames with addSecure = true

Test: VtsHalCameraProviderV2_4TargetTest passes on device without any secure only
      cameras
