this changes the API slightly to be more future-proof,
as we'll expose it in the SDK now.
The function now returns a SimpleTile constructor, rather than an
instance. This allows us to test if an entry would render in the
timeline without creating a tile, which is something we might want in
the matrix layer later on.
The function is now called tileClassForEntry, analogue to what we
do in TimelineView.
- [`linkedom`](https://github.com/WebReflection/linkedom) is being used https://github.com/matrix-org/matrix-public-archive to server-side render (SSR) Hydrogen (`hydrogen-view-sdk`)
- This is being fixed by using a explicit HTML wrapper boilerplate with `DOMParser` to get a matching result in the browser and `linkedom`.
Currently `parseHTML` is only used for HTML content bodies in events. Events with replies have content bodies that look like `<mx-reply>Hello</mx-reply> What's up` so they're parsed as HTML to strip out the `<mx-reply>` part.

Before:
```js
// Browser (Chrome, Firefox)
new DOMParser().parseFromString(`<div>foo</div>`, "text/html").body.outerHTML;
// '<body><div>foo</div></body>'
// `linkedom` ❌
new DOMParser().parseFromString(`<div>foo</div>`, "text/html").body.outerHTML;
// '<body></body>'
```
After (consistent matching output):
```js
// Browser (Chrome, Firefox)
new DOMParser().parseFromString(`<!DOCTYPE html><html><body><div>foo</div></body></html>`, "text/html").body.outerHTML;
// '<body><div>foo</div></body>'
// `linkedom`
new DOMParser().parseFromString(`<!DOCTYPE html><html><body><div>foo</div></body></html>`, "text/html").body.outerHTML;
// '<body><div>foo</div></body>'
```
`linkedom` goal is to be close to the current DOM standard, but [not too close](https://github.com/WebReflection/linkedom#faq). Focused on the streamlined cases for server-side rendering (SSR).
Here is some context around getting `DOMParser` to interpret things better. The conclusion was to only support the explicit standard cases with a `<html><body></body></html>` specified instead of adding the magic HTML document creation and massaging that the browser does.

on Android, by default (without the above attribute set to "send"), you
press enter twice to submit a field. The first time, enter, Android
seems to prevent sending logic by setting the key property on the event
to "Unidentified", but does insert a newline. The second consecutive enter,
it will be set to "Enter" and we'll send.
Having enterkeyhint to send will disable all of that. So we're going with
the default behaviour, which, IIRC, was a bit annoying on iOS as well.
