Minor refactor of built-in QSGVideoNodes.v5.5.0-beta1

- Load shader source from resource files.
- Correctly report material types: each material can use different
  shaders depending on the video pixel format but it was reporting
  a unique material type. This was causing the node to keep using
  the same shader even if its pixel format changed.
