Emily Martins c08986b026 Tests for CK Tile Batched Transpose and Smoothquant (#2453)
* Create tests for ck tile batched transpose using example

* Create ck tile tests for smoothquant using examples

* fix precision input strings and convert batched transpose to regression tests

* Code cleanup and fix asserts

* add missing licenses

* update copyright and licensing in files

* Update smoothquant tests to use example's smoothquant.cpp

* Add custom target for batched transpose tests

* Add missing new lines at end of files for CMakelists

* fix typo in batched transpose CMakeList target_compile_options
