Shubhanshu Saxena 08d8b3b631 lavfi/dnn_backend_tf: Request-based Execution
This commit uses TFRequestItem and the existing sync execution
mechanism to use request-based execution. It will help in adding
async functionality to the TensorFlow backend later.

Shubhanshu Saxena 6b961f7409 lavfi/dnn: Use uint8_t for async and do_ioproc in TaskItems
These properties have values either 0 or 1, so using uint8_t
is a better option as compared to int.

Guo, Yejun a3b74651a0 lavfi/dnn: refine dnn interface to add DNNExecBaseParams
Different function type of model requires different parameters, for
example, object detection detects lots of objects (cat/dog/...) in
the frame, and classifcation needs to know which object (cat or dog)
it is going to classify.

The current interface needs to add a new function with more parameters
to support new requirement, with this change, we can just add a new
struct (for example DNNExecClassifyParams) based on DNNExecBaseParams,
and so we can continue to use the current interface execute_model just
with params changed.
