[Feature] Automatically codegen client-code for supported languages

[notdanilo]

Is your feature request related to a problem? Please describe.
bolt build should also codegen the client-code for the supported languages

Describe the solution you'd like
TypeScript: Use Codama
C#: Use our C# codegen

This means we need to ship both tools with bolt-cli

I would keep it as a separate step, like bolt built-sdks or something similar, so that we don't slow down build and test too much. Also, not all users may be interested in generating the SDKs (we could not supporting explicitly atm)
