Only two commits from #18546 are backported. The remaining one is related to the fs error migration and should be backported differently, if worth backporting at all.

src: expose uv.errmap to binding
Refs: #17338

util: implement util.getSystemErrorName()
Refs: #18186

errors: improve the description of ERR_INVALID_ARG_VALUE
Refs: #18358

util: skip type checks in internal getSystemErrorName
errors: move error creation helpers to errors.js
Refs: #18546

Add a errno -> [error code, uv error message] map to the uv binding so the error message can be assembled in the JS layer. PR-URL: nodejs#17338 Reviewed-By: James M Snell <[email protected]> Reviewed-By: Ruben Bridgewater <[email protected]>
Reimplement uv.errname() as internal/util.getSystemErrorName() to avoid the memory leaks caused by unknown error codes and avoid calling into C++ for the error names. Also expose it as a public API for external use.

- Allow user to customize why the argument is invalid - Display the argument with util.inspect so null bytes can be displayed properly. PR-URL: nodejs#18358 Reviewed-By: James M Snell <[email protected]> Reviewed-By: Jon Moss <[email protected]>
This commit moves error creation helpers scattered around under lib/ into lib/internal/errors.js in the hope of being clearer about the differences of errors that we throw into the user land. - Move util._errnoException and util._exceptionWithHostPort into internal/errors.js and simplify their logic so it's clearer what the properties these helpers create. - Move the errnoException helper in dns.js to internal/errors.js into internal/errors.js and rename it to dnsException. Simplify it's logic so it no longer calls errnoException and skips the unnecessary argument checks. PR-URL: nodejs#18546 Reviewed-By: James M Snell <[email protected]>

All failures in CI seem to be related to other flakes.
