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)
