Previously, `wp_encode_emoji()` and `wp_staticize_emoji()` used inaccurate regular expressions to find emoji, and transform then into HTML entities or `<img>`s, respectively. This would result in emoji not being correctly transformed, or occasionally, non-emoji being incorrectly transformed.
This commit adds a new `grunt` task - `grunt precommit:emoji`. It finds the regex in `twemoji.js`, transforms it into a PHP-friendly version, and adds it to `formatting.php`. This task is also automatically run by `grunt precommit`, when it detects that `twemoji.js` has changed.
The new regex requires features introduced in PCRE 8.32, which was introduced in PHP 5.4.14, though it was also backported to later releases of the PHP 5.3 series. For versions of PHP that don't support this, it will fall back to an updated version of the loose-matching regex.
For short posts, the performance difference between the old and new regex is negligible. As the posts get longer, however, the new method is exponentially faster.

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.

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.

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].

Like its predecessor (`sanitize_text_field()`), `sanitize_textarea_field()` is a helper function to sanitise user input. As the name suggests, this function is for sanitising input from `textarea` fields - it strips tags and invalid UTF-8 characters, like `sanitize_text_field()`, but retains newlines and extra inline whitespace.

[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.

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.
