Add new render options for eevee under simplify menu

First one would be an option to disable normal maps. They can slow down the viewport when there's a lot. I use a GT-555M and there's times when not too many normal maps slow down the viewport significantly.

Second would be options found under the preferences in Viewport >> Textures (The two I find more useful are limit size and Anisotropic filtering) right now they're quite hidden under the preferences and they help boost performance in eevee as well.
