* Parameter set for "convolution" type GEMM.
*
* For a "convolution" GEMM, the GEMM parameters (M, K) are specified as if
* an im2row had been performed on the input tensor to generate the operand
* matrix, but instead this structure describes the convolution parameters
* such that this can be done on the fly.
*
* The parameters describe the convolution details - the notional shape of
* the input and output tensors, whether padding is to be applied, the size
* of the kernel and a constant value to be used for padding (needed for
* quantized tensors).
*
* The second part describes the layout of the input tensor in memory, which
* is assumed to be in NHWC format. This consists of a base pointer and
* strides for columns, rows and batches. 'multis' are not supported for
* convolution type GEMMs.
