Currently PowerShell uses a fair amount of generated code, for example:

• The default formatters are all autogenerated and there's discussion about refactoring them to improve startup performance already
• Much of the core interpreter was generated in Python many years ago. There has been discussion in the past about updating our dependency on the LightCompiler

Instead, we could keep generated code out of the checked-in files by defining it as generated at build time using .NET Source Generators.
