Automated g4 rollback of changelist 885555524.

*** Reason for rollback ***

Rolling back obj/stl decoder inclusion as sources due to broken windows build.

*** Original change description ***

Include obj and stl decoder plugins as sources in CMake builds.

This removes the need to load these decoders via mj_loadAllPluginLibraries when using MuJoCo built with CMake. Other plugins are unchanged.
