hiz: Add tests for depth tests when rendering to an FBO

Add three tests, in which the FBO has the following attachments:
    1. GL_DEPTH_ATTACHMENT: GL_DEPTH_COMPONENT24
    2. GL_DEPTH_ATTACHMENT: GL_DEPTH_COMPONENT24
       GL_STENCIL_COMPONENT: GL_STENCIL_INDEX8
    3. GL_DEPTH_STENCIL_ATTACHMENT: GL_DEPTH24_STENCIL8
