mesa: add EXT_dsa glEnabledIndexedEXT

The implementation uses _mesa_ActiveTexture to change the active texture unit and
then reset it.

It causes an unnecessary _NEW_TEXTURE_STATE but:
  - adding an index argument to _mesa_set_enable causes a lot of changes (~140 callers)
  - enable_texture (called by _mesa_set_enable) might cause a _NEW_TEXTURE_STATE
    anyway.
