* Add a LinAlg pass to convert 2D convolutions and quantized 2D
convolutions that have the `FHWC` filter channel ordering into a
transpose followed by 2D convolutions that have the `HWCF` channel
ordering.
* Add a lit test to check the semantics of the transformation are
correct for both quantized and unquantized variants.
