Add a gpu gemm reference kernel (#1528)

Browse Source 
* Add a gpu gemm reference kernel

* Switch to gpu reference in gemm examples

* Remove redundant arguments

* Update all related examples

* Update more examples

* Try less threads per block

* Try even less threads per block

* Add support for all matrix layouts

* Increase block size

* Clean up

* Remove hardcoded strides

* Clean up

* Try a column-major case

* Revert back to row-major

* Run both CPU and GPU veriffication
