So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global
removed. Unfortunately, jsdom now requires Symbol to be present for its internal
functionality so such a test is no longer possible. Instead, it's been migrated
to an iframe test with transpiled JavaScript.
This PR also enables us to use ECMAScript 2017 or newer in Node.js code.

Also, run `grunt npmcopy` to sync the "external" directory with dependencies
from package.json. For example, the Sinon library version didn't match.

PR #3869 added support for `<script type="module">` & some support for
the `nomodule` attribute but with no tests for `nomodule` and with the
attribute only respected on inline scripts. This commit adds support for
source-based scripts as well. It also adds tests for `nomodule`, including
making sure legacy browsers execute such scripts as they'd natively do - that's
the whole point of `nomodule` scripts, after all.

Old iOS & Android Browser versions support script-src but not nonce, making the
nonce test impossible to run. Browsers not supporting CSP at all are not
a problem as they'll skip script-src restrictions completely.

- getResponseHeader(key) combines all header values for the provided key into a
single result where values are concatenated by ', '. This does not happen for
IE11 since multiple values for the same header are returned on separate lines.
This makes the function only return the last value of the header for IE11.
- Updated ajax headers test to better cover Object.prototype collisions

Current width/height cssHook reads the computed position style even if not
necessary as the browser passes the scrollboxSize support test. That has been
changed.
This commit also makes the scrollboxSize support test in line with all others
(i.e. only return true or false) and changes the variable name in the hook
to make the code clearer.

The user agent of the iPad with iOS 11.3 on BrowserStack is missing the "iPhone"
part in the "iPhone OS 11_3" part. This commit makes the iOS regex accept such
(probably?) malformed UAs.
Edge sometimes doesn't execute module scripts. It needs to be investigated why
but for now, we're skipping the test to make our tests more stable.
Closes gh-4140
In Edge 14-16 setting a style property to a whitespace-only value resets it to
the default, forcing us to skip a relevant CSS test in Edge. Now that Edge 17
has fixed the issue we can re-enable this test there.

A whitelist is available so that some tests can be allowed to always succeed.
This is used only for ajax for now as it can be manually disabled in IE but

rAF logic was introduced almost three years ago relative to this commit,
as a primary method for scheduling animation (see gh-1578 pull).
With it there was two substantial changes - one was explicitly mentioned
and the other was not.
First, if browser window was hidden aka `document.hidden === true`
it would immediately execute all scheduled animation without waiting
for time pass i.e. tick time become `0` instead of 13 ms of a default value.
Which created possibility for circular executions in case if `complete`
method executed the same animation (see gh-3434 issue).
And the second one - since then there was two ways of scheduling animation:
with `setInterval` and `requestAnimationFrame`, but there was a
difference in their execution.
In case of `setInterval` it waited default `jQuery.fx.interval` value before
actually starting the new tick, not counting the first step which wasn't
set to be executed through tick method (aka `jQuery.fx.tick`).
Whereas `requestAnimationFrame` first scheduled the call and executed
the `step` method right after that, counting the first call of
`jQuery.fx.timer`, `tick` was happening twice in one frame.
But since tests explicitly disabled rAF method i.e.
`requestAnimationFrame = null` and checking only `setInterval` logic,
since it's impossible to do it otherwise - we missed that change.
Faulty logic also was presented with `cancelAnimationFrame`, which couldn't
clear any timers since `raf` scheduler didn't define new `timerId` value.
Because that change was so subtle, apparently no user noticed it proving
that both `cancelAnimationFrame` and `clearInterval` code paths are redundant.
Since `cancelAnimationFrame` didn't work properly and rAF is and was a primary
used code path, plus the same approach is used in other popular animation libs.
Therefore those code paths were removed.
These changes also replace two different functions which schedule the animation
with one, which checks what type of logic should be used and executes it
appropriatley, but for secondary path it now uses `setTimeout` making it more
consistent with rAF path.
Since ticks are happening globally we also don't require to listen
`visibilitychange` event.
It also changes the way how first call is scheduled so execution of
animation will not happen twice in one frame.
No new tests were not introduced, since now `setTimeout` logic should be
equivalent to the rAF one, but one test was changed since now we actually
execute animation at the first tick.
