Feature Request: Allow choosing to prefer esm entry or cjs entry

[xc2]

es module makes sense.

I'd prefer to:

• add an entry option to allow users to specify the entry point; or
• add a preferCondition: "import" | "require" option and use enhanced-resolve to resolve the entry.

Once we add a resolver library to the codebase, we can also use it to resolve the type declaration file more reliably.
