Add cl_khr_cooperative_matrix tests

Add tests for the `cl_khr_cooperative_matrix` extension.

The extension defines various operations on cooperative matrix types.
The list of tested operations is in `cooperative_matrix.def`.  Each
entry in that `.def` file results in a subtest.

Each subtest will iterate over all supported variants reported by the
runtime and test each variant.  An individual variant can be run using
the `--variant` command line option.

This CTS suite generates textual SPIR-V and uses spirv-tools to
assemble the textual SPIR-V into a SPIR-V binary.
