## 🔍 Overview
Previously we added the ability to translate existing posts in different
languages: https://github.com/discourse/discourse/pull/32564. In this
update we add the ability to set a post language upon initially creating
a post.
Internally, we also clean-up/improve a few things, like:
- adding a `PostLanguageSelector` component
- Adding a `available_content_localization_locales` onto `SiteSetting`
so it's available in the service (without needing to parse the JSON to
access it)
- fix issues with the translation-editor not working due to some
regressions from here: https://github.com/discourse/discourse/pull/32869
- ensure everything works for replies/drafts/edits

## 🔍 Overview
This update includes some small improvements to post localizations. In
particular:
- we only show add translation button if user is part of
`experimental_content_localization_allowed_groups` and
`SiteSetting.experimental_content_localization` is `true`
- we no longer load `post_localizations` on every post until the post
localization globe is clicked
- we move the post localization indicator to be an menu item in the
post-action-buttons instead of being in the post meta data
- we remove the `SiteSetting.content_localization_debug_allowed_groups`
in favor of using a single setting:
`experimental_content_localization_allowed_groups_map`

## 🔍 Overview
This update adds the ability for users to manually add translations to
specific posts. It adds a 🌐 icon on the post menu where you can click to
add translations for posts.
It also introduces a new site setting:
`content_localization_debug_allowed_groups` which is convenient when
debugging localized posts. It adds a globe icon in the post meta data
area along with a number of how many languages the post is translated
in. Hovering over the icon will show a tooltip with access to editing
and deleting the translated posts.

This commit adds
- `topic_localization` containing its topic, a locale, title, and
fancy_title
- `post_localization` containing its post, a locale, raw, cooked, the
associated post's version
- and also APIs to add them
Reviewer note: We may ask ourselves "why create separate models instead
of one that is generic?" but the different localizable models may be
vastly different. For example in posts we only have raw that we need to
translate, and topics we have only title, but for categories we have
name and description. Then, we may ask ourselves "why not create a
polymorphic one that takes in model and column name?" and then we end up
with the same thing as what we have currently which is custom fields
(which is a mess in itself). Also, when replacing the untranslated
content to the translated one, we may find it easier to just `join` +
`coalesce` on the dedicated table - it would be a much simpler query
than polymorphism.
