nouveau/codegen: Add a 4th optimization level for MemoryOpts

Browse source 
MemoryOpt optimization pass makes some tests in NVK fail. Until its
fixed in codegen or implemented on NIR instead, move it to a 4th level.
This affects the GL driver as well, but less often.

Fixes dEQP-VK.pipeline.monolithic.dynamic_control_points.change_output*
