Emoji picker to shared components (#34337)

* Exploration of a virtuoso-powered emoji picker

moved to shared components

Fable generated

* fix pnpm lock

* format & fix some lint issues

* wrong import

* fix lint warning

* Fix off-by-one

and remove manual overflow adjustment: let's leave the default unless
it turns out to be necessary. Emoji should not take that long to load.

* Convert to functional component

* WIP: change to one big virtuoso scroller

* Change to use virtuoso's own onRangeChanged

and santitise category data and how it's passed around

* Convert Tabs to functional component

and put the focusing behaviour back with it just keeping track of
refs by itself.

* Absorb two line config file into main component

* Actually add the config to the main file

* Convert emoji to functional

Also make selected always defined and use useCallback.

* QuickReactions to functional component

* Non-default exports & doc

* Search to functional component

* Well it seems to work just fine now

* Use ref prop

* fix lockfile AGAIN

* lint

* Remove default export

* Remove some mx_ classnames and fix the inputRef

to make the arrow keys in the search box work (well, work as much as
they ever did).

* Remove last of the mx_ id / classnames

(except the one in the test)

* Use useMemo to memoize

* No need to export props interface (I think?)

and fix comment now we don't do the mutation stuff anymore

* Fix test

* Fix axe violations & add screenshots

* Avoid comparing dom snapshots in test

* Allow more before or after, just compare order of the ones present in both.

* Switch existing usages to new emoji picker

and kill the old one with fire

* Unused stuff

* Remove i18n strings

* Fix some tests

* Update screenshots

* Fix test

by removing the last of the weird memoized-but-mutated data structure

* Move the string somewhere more sensible than 'a11y'

* i18n lint

* Give the emojis IDs so aria-activedescendant works

* Fix more tests

* Add a small wrapper emoji picker component

This lets us easily memoize the recent emojis when the emoji picker is opened.
Also it saves a bit of boilerplate.

* Remove old emojipicker css

* Typos
