fix(node): make readline Interface and Readline classes no-op stubs

[petebacondarwin]

Summary

• Change the readline Interface class and the readline/promises Interface and Readline classes to be no-op stubs instead of throwing errors
• Methods now return sensible defaults (empty strings, zero values, etc.) instead of throwing ERR_METHOD_NOT_IMPLEMENTED errors
• This matches the behavior of unenv's readline implementation, which allows code that depends on readline to work without crashing even though the functionality is not fully implemented

Fixes compatibility with cloudflare/workers-sdk#11734
