Josh Matthews c6c15d10b2 servo: Merge #12559 - Generate multiple DOM bindings in parallel (from jdm:parallel-codegen); r=Ms2ger
Reduces the time for a build after touching `CodegenRust.py` by 58s for me.

---
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix #12529 (github issue number if applicable).
- [X] These changes do not require tests because it's a build performance optimization
