Remove dead plugin scaffolds and duplicate lib dirs

The *_native C++ ports were replaced by bundled Python + .py plugins in
de4db79, but the source dirs were left behind without any CMake wiring —
causing confusion when editing them appears to do nothing. Same story
for libs/dds_header (stale duplicate of libs/preview_dds, unrelated to
the actively-used libs/dds-header) and libs/game_gamebryo (superseded
by libs/game_bethesda/src/gamebryo).

Removes:
- libs/basic_games_native
- libs/form43_checker_native
- libs/installer_omod_native
- libs/preview_dds_native
- libs/rootbuilder_native
- libs/script_extender_checker_native
- libs/dds_header
- libs/game_gamebryo
