chore: export error codes from subpackages

Discussed in #2669

There are numerous error codes available in libp2p package, in packages/libp2p/src/errors.ts. Is there a reason these error code are not exported neither in the interface package, nor in the libp2p package itself?
Currently there is no way to check caught error type against these codes other than duplicating the needed ones inside codebases using libp2p.
I also know that these codes are going to be refactored to error names in the future, but it doesn't make any difference. When the refactor occurs, the names should be exported the same way.

The discussion has two new comments, I think we may close this one as a result.
