Remove `Discourse` constant usage (#10470)

* REFACTOR: Get us closer to no `Discourse` constants in tests

* REFACTOR: Remove `Discourse.currentUser`

* REFACTOR: `prioritizeNameInUx` is really a helper and can use context

* REFACTOR: Rename test

* REFACTOR: Remove `Discourse.MarkdownItURL` and use session

* REFACTOR: Remove unused `LetterAvatarVersion`

* REFACTOR: Remove unused `Discourse.ThemeSettings`

* REFACTOR: Remove unused CDN constants

* REFACTOR: The `globalNotice` property doesn't exist anymore

* REFACTOR: Remove `Discourse.__container__` from plugin api

* REFACTOR: Consider `logout()` a helper and remove container.
