Use guest texture view type to determine the underlying image type

Browse Source 
If we have a Nx1x1 image then determining the type from dimensions will result in a 1D image being created thus preventing us from creating a 2D view. By using the image view type we can avoid this for textures from TICs since we know in advance how they will be used
