1. Adds a `libdevilution_so` target when tests are enabled. 2. Each test file is now a separate binary target linked against `libdevilutionx_so` (can now run tests in parallel). 3. Tests are now defined in a separate `test/CMakeLists.txt` file. 4. Building the tests is now controlled by the standard `BUILD_TESTING` option (defined by CTest). 5. Tests are now built by default. 6. On CI, test errors are now reported. Also: * `.clang-format`: Enable SortIncludes in tests * `path_test.cpp`: Fix -Wsign-compare
