Summary High system cpu load during IDL generation

On a M1 Ultra Mac Studio, WebCore’s derived sources target takes ~ 50sec to build, with most of that time spent generating IDLs. It scales to use all CPUs, but puts comparatively more load on the system than on user processes. We should figure out why this is such a system-heavy operation, and optimize it.
