Subject: [PATCH] Remove core-js polyfills (#14788)

According to engines.node in package.json, the minimal supported version
of Node.js is 14.

* `Object.fromEntries()` is supported by Node.js since 12.0.0
* `Array.prototype.flat()` is supported by Node.js since 11.0.0

These polyfills were added in #9085, but the minimum supported Node.js
version has since been raised to 14.
