Take into account the optimization level requested in TargetDesc (#2649)

* Take into account the optimization level requested in TargetDesc

Combines conflicting optimization levels by taking the maximum between them; as such they now each represent the lower bound on the eventual optimization level.

Most of the changes are making this clear by s/optimizationLevel/minimumOptimizationLevel

Closes https://github.com/shader-slang/slang/issues/2324

* Remove optimization level from TargetDesc
