Chris Tate 7dcb1e6c4e Lower util.promisify over the zlib callback one-shots

promisify(zlib.deflate) and the other callback one-shots (inflate,
deflateRaw, inflateRaw, gzip, gunzip, unzip) over a named or namespace
import of node:zlib now lower. A call through the binding,
gzipAsync(data, options?), runs the callback form's work on the worker
pool and returns a promise that settles where the callback would run:
fulfilled with the Buffer, or rejected with the callback form's Error
(errno, code and message). An invalid option or input rejects the promise
instead of throwing, as the throw inside Node's promisify wrapper does.

The runtime adds scr_zlib_codec_promise and its checked-dynamic twin,
which share the callback forms' options ladder and worker-pool operation
and settle a pending promise in place of the callback. The fallback
declarations gain the matching util.promisify overload.
