Remove focus management (#1953)

This PR removes the automatic focus events from the editor.

The `autoFocus` prop is now true by default. When true, the editor will
begin in a focused state (`editor.instanceState.isFocused` will be
`true`) and the component will respond to keyboard shortcuts and other
interactions. When false, the editor will begin in an unfocused state
and not respond to keyboard interactions.

**It's now up to the developer** using the component to update
`isFocused` themselves. There's no predictable way to do that on our
side, so we leave it to the developer to decide when to turn on or off
focus for a container (for example, using an intersection observer to
"unfocus" components that are off screen).

### Change Type

- [x] `major` — Breaking change

### Test Plan

1. Open the multiple editors example.
2. Click to focus each editor.
3. Use the keyboard shortcuts to check that the correct editor is
focused.
4. Start editing a shape, then select the other editor. The first
editing shape should complete.

- [x] Unit Tests
- [x] End to end tests

### Release Notes

- [editor] Make autofocus default, remove automatic blur / focus events.

<h1>White Board</h1>
<h2>Chapter 1: The First Strokes</h2>
<p>
The fluorescent lights flickered overhead as John sat hunched over his desk, his fingers
tapping rhythmically on the keyboard. He was a software developer, and tonight, he had a
peculiar mission. A mission that would take him deep into the labyrinthine world of web
development. John had stumbled upon a new whiteboard library called "tldraw," a
seemingly simple tool that promised to revolutionize collaborative drawing on the web.
Little did he know that this discovery would set off a chain of events that would
challenge his skills, test his perseverance, and blur the line between reality and
imagination.
</p>
<p>
With a newfound sense of excitement, John began integrating "tldraw" into his latest
project. As lines of code danced across his screen, he imagined the possibilities that
lay ahead. The potential to create virtual spaces where ideas could be shared, concepts
could be visualized, and teams could collaborate seamlessly from different corners of
the world. It was a dream that seemed within reach, a vision of a future where
creativity and technology merged into a harmonious symphony.
</p>
<p>
As the night wore on, John's mind became consumed with the whiteboard library. He
couldn't help but marvel at its elegance and simplicity. With each stroke of his
keyboard, he felt a surge of inspiration, a connection to something greater than
himself. It was as if the lines of code he was writing were transforming into a digital
canvas, waiting to be filled with the strokes of imagination. In that moment, John
realized that he was not just building a tool, but breathing life into a new form of
expression. The whiteboard was no longer just a blank slate; it had become a portal to a
world where ideas could flourish and dreams could take shape.
</p>
<p>
Little did John know, this integration of "tldraw" was only the beginning. It would lead
him down a path filled with unforeseen challenges, where he would confront his own
limitations and question the very nature of creation. The journey ahead would test his
resolve, pushing him to the edge of his sanity. And as he embarked on this perilous
adventure, he could not shake the feeling that the whiteboard held secrets far beyond
his understanding. Secrets that would unfold before his eyes, one stroke at a time.
