Fixes the UN flag not being correctly compared to itself, introduced in [40837].
Replaces the bearded person check with a male fairy. Emoji 5 does not have gendered bearded people, so we needed to switch it out to use the ZWJ check for a broken render.
Props peterwilsoncc for the code and commit message.

Updates Twemoji to 2.3.0 to include Emoji 5 support.
The pride flag test is replaced with a test for the English flag, a five character sub-devision locale. The UN flag test is retained as the most recent two character locale.
An Emoji 5 "bearded person" replaces both Emoji 4 tests.

Updates Twemoji and adds a second Emoji 4 test to include a shrugging man. Emoji 4 is being implemented gradually, while some browsers now support the female technologist, the indifferent shrugging man is breaking things with his presence.

Previously, the UN flag test relied on the image being produced to be quite small. Unfortunately, the Chrome PNG encoder seems to have changed recently, and it now produces a relatively large image.
For a better test, we can compare the rendering of [U] + [N] against [U] + zero width space + [N].

Improve performance of Emoji tests and loading of the polyfill.
Reduces the number of tests to determine browser support for emoji to those most likely to fail. Adds the defer flag to the loaded scripts for browsers lacking support.
Props superpoincare for perf testing, peterwilsoncc.

[38179] added support for the rainbow flag to core, but platform compatibility is a bit strange, because the flag was defined out of sync with the usual Unicode release cycle. For example Android N supports all Unicode 9.0 emoji, but doesn't support the rainbow flag thus the rainbow flag isn't rendered.
The Twemoji loader already has an exception for flags - it'll load if the browser supports everything but flags, and then only replace flag emoji, leaving everything else as native rendering. To provide a seamless experience for all flags the loader now uses the rainbow flag to test flag support.
Props pento.

This includes a new test in the emoji loader, to see if the browser supports rendering Unicode 9.0 emoji, as well as an update to `twemoji.js`, to load Unicode 9.0 twemoji images.
The default CDN location for loading Twemoji images has changed, moving to a versioned subdirectory. This allows updates without needing to purge the CDN.

[37028] missed some logic to capture the base emoji skin tone, to compare to the modified emoji skin tone. This caused all browsers to report that they supported skin tone modifiers, regardless of whether they actually did.

When the browser test for diversity emoji was added in [36160], it included a workaround for Chrome not being able to compare `Uint8ClampedArray` objects directly, by converting them to a string. Unfortunately, Safari doesn't support the `Uint8ClampedArray.toString()` method correctly, so the test was incorrectly failing in Safari.

As new sets of emoji are added to Unicode, and browsers add support for them at random intervals, we'll inevitably need to add new tests to the emoji loader. This change makes it much easier to add new tests as they're needed.
