Call this function to enqueue image upload operations to resourceUpdates, in case there are any pending ones.
When there is no new data (for example, because there was no setImage() since the last call to this function), the function does nothing.
Materials involving rhi textures are expected to call this function from their \l{QSGMaterialShader::updateSampledImage()}{updateSampledImage()} implementation, typically without any conditions, passing {state.rhi()} and {state.resourceUpdateBatch()} from the QSGMaterialShader::RenderState.
Reimplemented from QSGTexture.
