lc-compliance: Add a libcamera compliance tool

Add a compliance tool to ease testing of cameras. In contrast to the unit-tests under test/ that aims to test the internal components of libcamera the compliance tool aims to test application use-cases and to some extent the public API. This change adds the boilerplate code of a simple framework for the creation of tests. The tests aim both to demonstrate the tool and to catch real problems. The tests added are: - Test that if one queues exactly N requests to a camera exactly N requests are eventually completed. - Test that a configured camera can be started and stopped multiple times in an attempt to exercise cleanup code paths otherwise not often tested with 'cam' for example.
