Support for arbitrary strides

[dtarakanov1]

MIOpen supports data with the NCHW layout. A tensor descriptor works dimensions in the NCHW order.

A tensor descriptor also requires an array of strides (see e.g. miopenSetTensorDescriptor()).

However according to the kernel code there is no such parameter as a height stride, it is always assumed to be equal to 1. This means that if input data is in the NHWC format, they must be physically re-ordered. It's not possible to simply change the strides order to get MIOpen algorithms working.

@dtarakanov1 Thanks for your comment. Consistent striding is something we need to add across the library. Look for better support in the future releases.
