Add Setting to Allow For Slower or Less CPU Intensive Shader Compilation

When compiling shaders several of my i9-14900KF cores hit 95C+ during the process even with an AIO 360 cooler. This most recent (May 6 2026) patch had one core actually hit 99C. Since it only takes a few minutes to compile on this CPU I'd much rather it take 10-15 minutes and not hammer the cores so hard. If possible, please add a settings option that will allow you to limit the number of cores used, or a setting to reduce the amount each core is used to keep temperatures stable. This would allow those who don't mind the brief temp spikes to continue to compile at full speed and those who do mind to adjust to their preference. Thank you!
