glupload: add GST_CAPS_FEATURE_MEMORY_DMABUF

    glupload: add GST_CAPS_FEATURE_MEMORY_DMABUF

    Insert before SystemMemory to advice upstream elements that it is
    preferable for them to push dmabuf with the caps feature.

    Examples:

    /* Discard memory:DMABuf caps feature */
    GST_GL_PLATFORM=egl GST_GL_API=gles2 GST_GL_WINDOW=x11 gst-launch-1.0 \
        filesrc location=test.mp4 ! qtdemux ! h264parse ! vaapih264dec ! \
        capsfilter caps="video/x-raw(memory:SystemMemory)" ! glimagesink

    /* Force memory:DMABuf caps feature. */
    GST_GL_PLATFORM=egl GST_GL_API=gles2 GST_GL_WINDOW=x11 gst-launch-1.0 \
        filesrc location=test.mp4 ! qtdemux ! h264parse ! vaapih264dec ! \
        capsfilter caps="video/x-raw(memory:DMABuf)" ! glimagesink

    /* Auto select memory:DMABuf caps feature.  */
    GST_GL_PLATFORM=egl GST_GL_API=gles2 GST_GL_WINDOW=x11 gst-launch-1.0 \
        filesrc location=test.mp4 ! qtdemux ! h264parse ! vaapih264dec ! \
        glimagesink
