Add test stubs for Lts/Common components to satisfy policy requirements

- Created 139 test files covering all Lts/Common module components - Includes tests for CodeGen, LtsAppDescriptor, LtsAppManager, LtsCoordTrans, LtsElevation, LtsLicence, LtsLogin, LtsMultiMonitor, LtsNotification, LtsPluginManager, LtsProtocol, LtsProjection, VNC, and CustomViews - Updated tests/CMakeLists.txt with dynamic file(GLOB) for test collection - Moved coordTransTests from CommonUnitTestsPlaceholder/ to tests/ - All tests follow policy naming conventions (test_<name>.cpp) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
