Emoji: Fix defects in emoji scripts and add type checking.
Several defects in `wp-emoji.js` had gone unnoticed because neither emoji script was type checked nor tested:
* Since 4.4, the fallback for an emoji image which fails to load has never worked. The `onerror` handler given to Twemoji referred to the library object instead of the image element, leaving a broken image icon in place of the emoji character.
* Because that handler never set the `data-error` attribute, the `MutationObserver` guard which recognizes such a replacement was unreachable, hiding the fact that it abandoned all remaining mutation records rather than only the one it recognized. It is corrected along with the handler, since fixing the handler alone would cause an element added in the same batch as a failed image to go unparsed.
* An added `<svg>` or MathML element was handed to Twemoji, which put `<img>` elements inside it.
* The `wp-exclude-emoji` class was matched as a substring of the `class` attribute rather than as a class, so classes such as `my-wp-exclude-emoji` also excluded an element.
Code which could not run in any browser able to load the script is removed:
* The IE 11 workaround.
* The `browserSupportsSvgAsImage()` check, whose call to `document.implementation.hasFeature()` always returns `true` per the DOM standard, so the PNG fallback was unreachable.
* The vendor-prefixed `MutationObserver` detection.
The rest of `wp-emoji.js` is modernized to match the emoji loader, which was already updated in r60899.
Both scripts are added to the files checked by `tsc`, with new typings for the settings exported by `_print_emoji_detection_script()`, the vendored Twemoji library, and `WorkerGlobalScope`, which the `dom` lib does not provide. Annotating the loader's support tests precisely made `browserSupportsEmoji()` exhaustively checked, and `allowUnreachableCode` is disabled so that unreachable code is reported on the command line and not just in editors. The first QUnit tests for `wp-emoji.js` are added, covering each defect fixed here. The loader remains untested because it exports nothing and runs on import, leaving no seam to test through.
Developed in https://github.com/WordPress/wordpress-develop/pull/13592.
Follow-up to r35637, r36817, r37471, r55186, r60899, r60902.
