uv_fs_lchown() exists, as of libuv 1.21.0. fs.lchown() can now
be undeprecated. This commit also adds tests, as there were
none.

Notable changes:
* build:
  * Node.js should now be about 60% faster to startup than the previous version,
    thanks to the use V8's code cache feature for core modules. [#21405](#21405)
* dns:
  * An experimental promisified version of the dns module is now available. Give
    it a try with `require('dns').promises`. [#21264](#21264)
* fs:
  * `fs.lchown` has been undeprecated now that libuv supports it. [#21498](#21498)
* lib:
  * `Atomics.wake` is being renamed to `Atomics.notify` in the ECMAScript
    specification ([reference](tc39/ecma262#1220)).
    Since Node.js now has experimental support for worker threads, we are being
    proactive and added a `notify` alias, while emitting a warning if
    `wake` is used. [#21413](#21413) [#21518](#21518)
* n-api:
  * Add API for asynchronous functions. [#17887](#17887)
* util:
  * `util.inspect` is now able to return a result instead of throwing when the
    maximum call stack size is exceeded during inspection. [#20725](#20725)
* vm:
  * Add `script.createCachedData()`. This API replaces the `produceCachedData`
    option of the `Script` constructor that is now deprecated. [#20300](#20300)
* worker:
  * Support for relative paths has been added to the `Worker` constructor. Paths
    are interpreted relative to the current working directory. [#21407](#21407)
