Refactor image view extent retrieval

Image views are only accessed by shaders, and we've previously ensured descriptors only have one field for holding either the depth of a 3D texture or the array layer count. This value is accessed through the getDepthOrLayerCount() method, and so the getMipLevelExtent() of the ImageView class only has to return the 2D extent.
