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

src: expose uv.errmap to binding
017013a 
Add a errno -> [error code, uv error message] map to the uv binding
so the error message can be assembled in the JS layer.

util: implement util.getSystemErrorName()
3b18dae 
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.

errors: move error creation helpers to errors.js
714c529 
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.
