Add Queries and Setters for resource initialization state. There are cases where we know that the next draw operation will fully initialize a texture/renderbuffer and we can save the robust resource init cost. Default all resource init state to Initialized, any redefinition will set it back to MayNeedInit. After setting an individual texture image to initialized, check if all images are now initialized and update the TextureState::mInitState to match. The cost of this check is only performed after initializing an image and allows future init checks to be faster.
