Add checkboxes in developer tools to allow disabling ubershaders

Separately for Vertex/Fragment. Might be helpful to diagnose performance problems on user devices.

Additionally, moves the texture replacement controls to the top. They should probably be moved somewhere else entirely...

See #17918

just want to say thank you.😁
disable this Vertex & Fragment, Very helpful for playing the God of War series.
i tried it on sharp dimensity 700, got 60fps if i disable Vertex & Fragment, The fps will drop a little if I record the screen for just a moment.
