Remove STUB files, use real dependencies

- Removed all STUB files for external dependencies:
  - lts_session_stub.h/cpp
  - lts_session_data_dds_stub.h/cpp
  - lts_session_lock_handler_stub.h
  - elevation_map_manager.h/cpp (entire ElevationMap STUB)
  - avm_enums_stub.hpp
  - Test files for STUBs

- Updated LtsSession/CMakeLists.txt:
  - Removed conditional BUILD_RTI logic for STUBs
  - Always use real implementation files
  - BUILD_RTI=ON is now the default

- External dependencies are now expected in ./external/
  - RTI Connext DDS 7.7.0
  - ArcGIS SDK (runtime mount)
  - Other deps to be integrated step by step
