doxygen docs: remove @ender_group and organize eina vectors

Mysterious @ender_group is an invalid doxygen command and I could not find
it defined anywhere. I could not infer its purpose either so... removed.
Put the Eina Vector 2D and 3D groups in their proper place so they appear
with the rest of the Eina basic types.
