GL: don't accidentally skip CubeMapTexture creation on no-assert builds. 

In all other cases this is called outside of #ifndef CORRADE_NO_ASSERT,
so this is likely some yet-undiscovered copypaste error. OTOH it's such a
corner case of a corner case that I don't think anyone ever hits that
because it'd fail on just anything else anyway:

    GL::CubeMapTexture texture;
    // nothing done here, not even a format / size specified
    texture.compressedSubImage(...);

This extra call originates in ae70a62644
(2015, again) and was used in all places where DSA functions were called
directly without feature-aware dispatch. Since then, some of the cases
were turned into feature-aware dispatches, which means the call isn't
needed in those anymore, so I removed it. And to clarify why is it needed
in the remaining cases I added extra comments.
