[cogl] texture: removes cogl_texture_new_from_sub_texture

    texture: removes cogl_texture_new_from_sub_texture
    
    cogl_texture_new_from_sub_texture is redundant since it's just a thin
    wrapper around cogl_sub_texture_new() which relies on the
    _COGL_GET_CONTEXT() macro we are trying to eradicated. This patch removes
    the wrapper.
