✨ Introduce DioExceptionLogBuilder

[AlexV525]

Resolves #1949
Resolves #2287

Developers may want the URL of the exception to know what endpoint has gone wrong, or they want to have fewer tips about what the status code means. If we open too many flags to support various logging content, it will be a mess eventually.
Introducing the DioExceptionLogBuilder easily builds text content from the DioException.

I think this is good, same goes for the log level.
