URL polyfill for Safari 13+

[dilyanpalauzov]

With these files bbb.json:

{
  "presets": [
    [
      "@babel/preset-env",
	{
	    "bugfixes": true,
	    "corejs": 3,
	    "modules": false,
	    "targets": "safari > 13.1", 
	    "useBuiltIns": "usage"
      }
    ]
  ]
}

and xxx.js:

new URL('https://x.y.z');

calling babel --config-file ./bbb.json xxx.js produces

import "core-js/modules/web.url";
new URL('https://x.y.z');

https://caniuse.com/url and https://caniuse.com/urlsearchparams have no concerns.

Why is the polyfill necessary for Safari?

Hey @dilyanpalauzov! We really appreciate you taking the time to report an issue. The collaborators on this project attempt to help as many people as possible, but we're a limited number of volunteers, so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack community that typically always has someone willing to help. You can sign-up here for an invite."

We use core-js-compat as the data source for core-js 3, please ask the question in the core-js repository.

Usually it's a browser bug that core-js fixes but isn't listed in caniuse.

Ok, it's needed for zloirock/core-js#656
