Make the library which generates CK instances for pytorch2 inductor's CK backend usage

Also bundle the CK library and include files with the pip package.

The package is pip-installable with
`pip install
git+https://github.com/tenpercent/composable_kernel@enable-pip`

(substitute the repo path and branch if necessary)

Testing:

`myenv/bin/python3 -m ck4inductor.universal_gemm.gen_instances`

(prints a list of instances)

`tree myenv/lib/python3.12/site-packages/ck4inductor`

(observe the list of sources along the installed package)
