c636dc9819 libavfilter/dnn: add more data type support for dnn model input
currently, only float is supported as model input, actually, there
are other data types, this patch adds uint8.

25c1cd909f libavfilter/dnn: support multiple outputs for tensorflow model
some models such as ssd, yolo have more than one output.

the clean up code in this patch is a little complex, it is because
that set_input_output_tf could be called for many times together
with ff_dnn_execute_model_tf, we have to clean resources for the
case that the two interfaces are called interleaved.

e2b92896c4 libavfilter/dnn: determine dnn output during execute_model instead of set_input_output
Currently, within interface set_input_output, the dims/memory of the tensorflow
dnn model output is determined by executing the model with zero input,
actually, the output dims might vary with different input data for networks
such as object detection models faster-rcnn, ssd and yolo.

This patch moves the logic from set_input_output to execute_model which
is suitable for all the cases. Since interface changed, and so dnn_backend_native
also changes.

In vf_sr.c, it knows it's srcnn or espcn by executing the model with zero input,
so execute_model has to be called in function config_props
