Subject: lib: remove internal `util._extends()` usage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This removes all internal calls to the deprecated `_extends()`
function. It is slower than `Object.assign()` and the object spread
notation since V8 6.8 and using the spread notation often also
results in shorter code.
