zlib: convert classes to modern syntax and eol DEP0184

Convert ZlibBase, Zlib, and the remaining zlib/Brotli stream constructors
to ES6 class syntax. Calling these constructors without `new` is no longer
supported (DEP0184 End-of-Life); use `new` or the create* factory helpers
instead.

This is a semver-major change: code that relied on `zlib.Gzip()` (without
`new`) will now throw TypeError. The createGzip/createDeflate/... helpers
and all documented `new`-based usage remain unchanged. The wire behavior
and public options are preserved.
