Enhance(frontend): MFMや絵文字が使える入力ボックスでオートコンプリートを使えるように (#12643)

* rich autocomplete for use in profiles, announcements, and channel descriptions

* implementation omissions

* add tab, apply to page editor, and fix something

* componentization

* fix nyaize doesn't working in profile preview

* detach autocomplete instance when unmounted

* fix: mismatched camelCase

* remove unused / unnecessary styles

* update CHANGELOG.md

* fix lint

* remove dump.rdb

* props.richAutocomplete -> autocomplete

* Update packages/frontend/src/scripts/autocomplete.ts

* clarify namings
メンションなども「MFM」に含まれるのか自信がなかったのでrichSyntaxなどとぼかしていましたが、含むようなので変更しました

* tweak

* Update MkFormDialog.vue

* rename
