CMake: optionally disable OBJ, STL & GPencil SVG support

The following CMake options have been added (enabled by default),
except for the lite build configuration.

- WITH_IO_STL
- WITH_IO_WAVEFRONT_OBJ
- WITH_IO_GPENCIL (for grease pencil SVG importing).
  Note that it was already possible to disable grease pencil export
  by disabling WITH_PUGIXML & WITH_HARU.

This is intended to keep the lite builds fast and small for building,
linking & execution.
