Tests: Reorganize LibCompress unit tests
Move LibCompress unit tests to LibCompress/Tests directory and register them with CMake's add_test. This allows us to run these tests with ninja test instead of running a separate executable. Also split the existing tests in 3 test files that better follow the source code structure (inspired by AK tests).
