Fix https://github.com/vector-im/element-web/issues/21262
Optimizations:
1. Don't update the `style` (positioning) of hidden tooltips
1. Don't add DOM elements to the page for hidden tooltips
> ## Performance problems broken down
>
>
> ### Hidden tooltips rendering on `scroll`
>
> You can see that the Tooltip render is attached to the `scroll` event at [`src/components/views/elements/Tooltip.tsx#L78-L81`](31f0a37ca2/src/components/views/elements/Tooltip.tsx (L78-L81))
>
> The rendering calls [`src/components/views/elements/Tooltip.tsx#L101` -> `updatePosition`](36adba101c/src/components/views/elements/Tooltip.tsx (L101)) which ends up as an expensive "Recalculate Style" because it uses [`Element.getBoundingClientRect()`](https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect). This happens many many times within a single `scroll` event. Probably once for each tooltip within the room list **even though no tooltips are event visible as I scroll**. I can see that we're just updating the `style` attribute for a bunch of `.mx_Tooltip_invisible` elements at the end of the document.
>
> Each one of the purple spans below the `scroll` span ends up as a call to `updatePosition`. And a `scroll` event takes 35ms to 60ms to complete which is way over the 16.6ms 60 FPS budget (on a powerful desktop PC), granted these times are with the performance profiling running. This is without the Passbolt extension explained below.
>
> And the room list contains about 141 rooms (`document.querySelectorAll('.mx_RoomTile').length`):

> ### Passbolt Chrome browser extension exacerbates the problem
>
> In order to login to Passbolt, it requires a browser extension which defaults to mucking up all pages:

>
>
> The extension source seems to be available: https://github.com/passbolt/passbolt_browser_extension
>
> The Passbolt Chrome extension has a `MutationObserver` listening to all attribute and element changes to the whole `<body>` of the `document` so it can `findAndSetAuthenticationFields` (find form elements and autofill).
>
>
> [`passbolt/passbolt_styleguide` -> `src/react-web-integration/lib/InForm/InFormManager.js#L143`](1c5eddc910/src/react-web-integration/lib/InForm/InFormManager.js (L143))
> ```js
> this.mutationObserver.observe(document.body, { attributes: true, childList: true, subtree: true });
> ```
>
> This causes a bunch of `Forced reflow` because the Tooltip `updatePosition` is mutating the element `style` attribute and Passbolt `MutationObserver` callbacks are querying the whole DOM looking for form elements all in the same frame.
>
> Under the `scroll` event, all of the little spans are the `MutationObserver` -> `findAndSetAuthenticationFields`. With the Passbolt extension, scrolling is verrrrry crunchy and bad.
>
> 
>
>
> #### Workaround
>
> Instead of running Passbolt on all sites, we can enable the extension to only run on the domain for Passbolt instance itself. I'm guessing the Passbolt extension also does autofill stuff on sites but I always login manually to the Passbolt instance so this solution works for me �

> **Extensions** -> **Passbolt** -> **Details** -> Change **Site access** to `On specific sites` -> Enter in your Passbolt instance `https://passbolt.example.com/`

* UIComponent flag: Explore rooms
To disable the room directory access on the Home space. Can be controlled with the existing ComponentVisibilityCustomisation
* Make "plus menu" respect component visibility
* UIComponent flag: Add integrations
To disable the widgets section of the room info card and addwidget slashcommand. Can be controlled with the existing ComponentVisibilityCustomisation

* Clean up asserted identity code
Add logging when we received asserted identity events but ignore them,
and just disable the whole code path if it's not enabled in the config.
* Actually, put the check back - better to check anyway
* Update to ? syntax

* Add support for overriding strings in the app
This is to support a case where certain details of the app need to be slightly different and don't necessarily warrant a complete fork.
Intended for language-controlled deployments, operators can specify a JSON file with their custom translations that override the in-app/community-supplied ones.
* Fix import grouping
* Add a language handler test
* Appease the linter
* Add comment for why a weird class exists
* Add support for redirecting to external pages after logout
This is primarily useful for deployments where the account is managed and needs to be logged out in other places too, like an SSO system.
See docs for more information.
* Add e2e test and fix Windows instructions
* Fix performance gathering stats
* use logger
