Chore: Migrate build to vite (#1033)

* Chore: Add move most types from rrweb to @rrweb/types package

* Split off type imports

* Split off type import to its own line

* Get vite to generate type definitions

* Apply formatting changes

* noEmit not allowed in tsconfig, moved it to build step

* Migrate rrdom-nodejs build to vite

* Apply formatting changes

* Migrate rrweb-snapshot to vite

* Unify configs

* Chore: Migrate rrdom to vite

Turns out what we where doing by overwriting `public textContent: string | undefined` as a getter in a subclass is something that isn't allowed in typescript. Because we where using `// @ts-ignore`  to hide this error our bundler chose to allow the overwrite. Vite choses to disallow the overwrite making all subclasses' `textContent` undefined.
To mitigate this we're using an abstract class, which does allow sub classes to decide if they wan't to use getters or not.

* Chore: Migrate rrweb to vite WIP

* build:browser was removed (for now)

* BREAKING: moved rrweb-plugin-console to its own npm module

This removes console from rrweb-all.js

* Support cjs files in startServer

* Move canvas-webrtc plugin to its own package

* Chore: move sequential-id plugin to its own package

* Chore: Configure rrweb's vite bundling

* `Id` had lowercase `d` before, making it lowercase again

* Test: Move console tests to their own package

* remove unused utils from rrdom

* pull in latest version of master
something when wrong earlier when resolving merge conflicts, this should be correct

* Fix type casting issue in diff.ts

* Fix typo

* Fix duplicate entries in package.json and tsconfig.json

* Apply formatting changes

* Update dependencies in package.json files

* Update dependencies to use Vite 5.2.8 in package.json files

* Get tests passing for rrdom

`apply virtual style rules to node` tests need to be moved to rrweb to avoid circular dependencies

* Fix image loading issue in integration tests

* Move pack/unpack to its own @rrweb/packer module

* Get tests to work in rrdom-nodejs

* Port tests in rrweb-snapshot to vitest and fix them

* Fix tests for rrweb-plugin-console-record

* Add @rrweb/all package

* Fix publint and attw errors for rrdom and @rrweb/types

* Use shared vitest.config.ts in rrweb-snapshot package

* Fix publint and attw issues for rrweb-snapshot

* Export `ReplayPlugin` type directly from rrweb

* Fix publint and attw issues for packages

* Fix publint & attw issue.

I was bumping into this issue: 3729bc2a3c/docs/problems/NoResolution.md

And had to choose one of these three methods described here:
https://github.com/andrewbranch/example-subpath-exports-ts-compat?tab=readme-ov-file#typescript-friendly-strategies-for-packagejson-subpath-exports-compatibility
And I ended up going for the method described here:
1ffe3425b0/examples/node_modules/package-json-redirects (package-json-redirects)

The redirect method seemed the least invasive and most effective.

* Fix publint & attw issue.

# rrweb canvas webrtc plugin
Plugin that live streams contents of canvas elements via webrtc
## Example of live streaming via `yarn live-stream`
https://user-images.githubusercontent.com/4106/186701616-fd71a107-5d53-423c-ba09-0395a3a0252f.mov
## Instructions
### Record side
```js
// Record side
import rrweb from 'rrweb';
import { RRWebPluginCanvasWebRTCRecord } from '@rrweb/rrweb-plugin-canvas-webrtc-record';
const webRTCRecordPlugin = new RRWebPluginCanvasWebRTCRecord({
signalSendCallback: (msg) => {
// provides webrtc sdp offer signal & connect message
// make sure you send this to the replayer's `webRTCReplayPlugin.signalReceive(signal)`
sendSignalToReplayer(msg); // example of function that sends the signal to the replayer
},
});
rrweb.record({
emit: (event) => {
// send these events to the `replayer.addEvent(event)`, how you do that is up to you
// you can send them to a server for example which can then send them to the replayer
sendEventToReplayer(event); // example of function that sends the event to the replayer
},
plugins: [
// add the plugin to the list of plugins, and initialize it via `.initPlugin()`
webRTCRecordPlugin.initPlugin(),
],
recordCanvas: false, // we don't want canvas recording turned on, we're going to do that via the plugin
});
```
### Replay Side
```js
// Replay side
import rrweb from 'rrweb';
import { RRWebPluginCanvasWebRTCReplay } from '@rrweb/rrweb-plugin-canvas-webrtc-replay';
const webRTCReplayPlugin = new RRWebPluginCanvasWebRTCReplay({
canvasFoundCallback(canvas, context) {
console.log('canvas', canvas);
// send the canvas id to `webRTCRecordPlugin.setupStream(id)`, how you do that is up to you
// you can send them to a server for example which can then send them to the replayer
sendCanvasIdToRecordScript(context.id); // example of function that sends the id to the record script
},
signalSendCallback(signal) {
// provides webrtc sdp offer signal & connect message
// make sure you send this to the record script's `webRTCRecordPlugin.signalReceive(signal)`
sendSignalToRecordScript(signal); // example of function that sends the signal to the record script
},
});
const replayer = new rrweb.Replayer([], {
UNSAFE_replayCanvas: true, // turn canvas replay on!
liveMode: true, // live mode is needed to stream events to the replayer
plugins: [webRTCReplayPlugin.initPlugin()],
});
replayer.startLive(); // start the replayer in live mode
replayer.addEvent(event); // call this whenever an event is received from the record script
