s8 SVDF function with 8 bit state tensor and 8 bit time weights

Parameters
[in,out]ctxFunction context (e.g. temporary buffer). Check the function definition file to see if an additional buffer is required. Optional function arm_fully_connected_s8_get_buffer_size() provides the buffer size if an additional buffer is required. The caller is expected to clear the buffer, if applicable, for security reasons.
[in]input_ctxTemporary scratch buffer The caller is expected to clear the buffer, if applicable, for security reasons.
[in]output_ctxTemporary output scratch buffer The caller is expected to clear the buffer, if applicable, for security reasons.
[in]svdf_paramsSVDF Parameters Range of svdf_params->input_offset : [-128, 127] Range of svdf_params->output_offset : [-128, 127]

[in]input_dimsInput tensor dimensions
[in]input_dataPointer to input tensor
[in]state_dimsState tensor dimensions
[in]state_dataPointer to state tensor
[in]weights_feature_dimsWeights (feature) tensor dimensions
[in]weights_feature_dataPointer to the weights (feature) tensor
[in]weights_time_dimsWeights (time) tensor dimensions
[in]weights_time_dataPointer to the weights (time) tensor
[in]bias_dimsBias tensor dimensions
[in]bias_dataPointer to bias tensor
[in]output_dimsOutput tensor dimensions
