feat: implement rfc9110 http status names

[mbeijen]

Summary

rfc9110 obsoletes the earlier rfc 7231. This document also includes some status codes that were previously only used for WebDAV and assigns more generic names to these status codes.

ref: https://www.rfc-editor.org/rfc/rfc9110.html#name-changes-from-rfc-7231

The status code constants are updated to reflect the new naming and the old constants are kept for backwards compatibility

• HTTP_413_CONTENT_TOO_LARGE, previously HTTP_413_REQUEST_ENTITY_TOO_LARGE
• HTTP_414_URI_TOO_LONG, previously HTTP_414_REQUEST_URI_TOO_LONG
• HTTP_416_RANGE_NOT_SATISFIABLE, previously HTTP_416_REQUESTED_RANGE_NOT_SATISFIABLE
• HTTP_422_UNPROCESSABLE_CONTENT, previously HTTP_422_UNPROCESSABLE_ENTITY
