Basic CMake build

- Automatically add simple modules with pw_auto_add_simmple_module.
- Define libraries in a module with pw_add_module_library.
- Define tests and test groups with pw_add_test and
  pw_add_test_to_groups.
- Tests execute with full Ninja dependency resolution, as in the GN
  build.
- Add CMakeLists.txt for existing modules.
- Currently there is no support for targets, but these libraries would
  be trivial to integrate with an existing CMake build.
