Enable building with one less processor #1931

Running the various scripts, builds, consumes all processors creating a slow inner-loop Windows developer experience. (File Explorer can even time out and crash.) I don't think we'll see significant slowdowns with one less processor configured.

I believe the parallelism is handled via the below code.

https://github.com/microsoft/win32metadata/blob/97db7a1a021f1fb397ff52ab6df38cbbd88fcc1d/sources/GeneratorSdk/MetadataTasks/ScrapeHeaders.cs#L114-L141

I don't see MaxProcessors set anywhere, so in theory the build should only use half of your processors. Can you confirm what behavior you're seeing?

Not needed at this time, can revisit later.
