net: report detailed DNS errors with Extended DNS Errors

[mateusz834]

Before, when the query failed we returned a simple "server misbehaving"
error, with this change the go resolver will report detailed errors
with the use of the EDE extension found in the OPT resource.
Given that resolvers are now starting to support this EDNS(0) option,
I think it is worth to support it in the pure go resolver.

Fixes #63192
