Add torch kit

[pfultz2]

Motivation

To provide a stable set of operators to external tools like torch_migraphx through the op builder(or macro) interface.

Technical Details

This creates a "kit" which is a collection of op builders that essentially are wrappers around our current operators or op builders which all have a namespace(like tm:: for this case). If change or remove operators then we can update the kit to use some kind of op builder to achieve the same behavior.
