QOpenGLTexture::setData add overloads to allow specifying sub images

All current setData implementation only allow to specify a full size
sub image for a given mip level. In some cases, we might only want
to update a small region on an image, in which cases being able to
specify the x, y, z offsets as well as the dimensions is required.
