[MLIR] Single lit config attribute for CMAKE_LIBRARY_OUTPUT_DIRECTORY

Replace the following config attributes with `mlir_lib_dir`:
- `mlir_runner_utils_dir`
- `linalg_test_lib_dir`
- `spirv_wrapper_library_dir`
- `vulkan_wrapper_library_dir`
- `mlir_integration_test_dir`

I'm going to clean up substitutions in separate changes.
