refactor: classify tests into unit/integration/infer tiers

- Unit tests (BUILD_TESTS=ON, default): types, framework, domain, libs
- Integration tests (BUILD_INTEGRATION_TESTS=OFF): TestAppShellIntegration, dsfw-widgets-test
- Infer tests (*_BUILD_TESTS=OFF): TestGame, TestRmvpe, TestAudioUtil
- Default build now only compiles unit tests (~20 targets fewer)
