refactor(pnp): normalize resolve.exports errors

[paul-soporan]

What's the problem this PR addresses?

The errors thrown by the resolve.exports package weren't wrapped, causing us to display stack traces that included unnecessary information.

How did you fix it?

Wrapped the resolve.exports errors so that they can have pnpCode and data properties (and a code property too, but lukeed/resolve.exports#6 is required for proper validation and error codes).

I also added the extensions property to the data of QUALIFIED_PATH_RESOLUTION_FAILED errors for consistency.
