Improved the way test suites are executed

The main change is that `test_all.py` is now renamed to `run_suite.py`,
with the latter being able to run a selected test suite if a corresponding
command line argument (test suite directory name) is provided.

CMakeLists are improved to copy each test suite separately to avoid
copying unnecessary files. Also each test suite corresponds now to
a separate CMake test.
