…me linear to the number of channels (vs quadratic). Note that complexity of `extract_patches` is quadratic in the number of channels `C`, while `lax.conv_general_dilated_patches` is linear due to using depthwise convolution. AFAIK `extract_image_patches` has the same linear complexity, but can be shortened by calling to `lax.conv_general_dilated_patches` as well. PiperOrigin-RevId: 495102958
