This commit updates all defines, compiler flags and cleans up some code for unused CPU capabilities. There should be no functional change, unless it's run on a CPU that supports sse41 but not sse42. It will fallback to the SSE2 kernel in this case. In preparation for the new SSE4.2 minimum in Blender 4.2. Pull Request: https://projects.blender.org/blender/blender/pulls/118043
