chore: migrate tests to vitest (#3381)
managed to migrate the engine leak & memory reporters, although it took a bit of rigamarole. Mainly because, as opposed to karma, the reporter runs in node and not the browser. So I have to track the data needed separately in some global hooks _within_ the browser environment, which the reporter then reads and creates the logs if needed.
However, it seems the memory tracking is regularly reporting >1 mb, so I'm not sure if it's tracking properly or if things have changed with the new browsers. My only theory is that because the timing where memory is read is during an `afterEach` _before_ the test's `afterEach`, it's running before any potential cleanup. The timing of this is not something that's easy to control, unfortunately. I did try to prove this theory by doing the memory analysis on the next test's `beforeEach`, but it didnt seem to change the results, so it may not be an issue.
Implementation is done in `src/spec/vitest/__reporters__/memory.ts` and `src/spec/vitest/__reporters/memory.setup.ts`
---
I noticed CouroutineSpec was an offender for >10mb memory, which spins up additional engines. I added a short 100ms wait after the engine.dispose and the memory usage did drop, so it does seem like this is prone to scheduled garbage collecting.
---
I was able to run the garbage collector (if exposed, currently only on chrome) and this makes the reports more accurate

feat: Excalibur Scene Transitions & Loaders (#2790)
This PR implements an API inspired by https://github.com/mattjennings/excalibur-router/ with permission from Matt.
The idea behind this refactoring is to add transitions between scenes and scene specific loaders!
* Add or remove scenes by constructor
* Add loaders by constructor
* New `DefaultLoader` type that allows for easier custom loader creation
* New `Transition` type for building custom transitions
* New scene lifecycle to allow scene specific resource loading
* `onTransition(direction: "in" | "out") {...}`
* `onPreLoad(loader: DefaultLoader) {...}`
* New async goto API that allows overriding loaders/transitions between scenes
* Scenes now can have `async onInitialize` and `async onActivate`!
* New scenes director API that allows upfront definition of scenes/transitions/loaders
View [this file](https://github.com/excaliburjs/Excalibur/blob/feat/async-init-ex-router/sandbox/tests/router/index.ts) for a current example of what the API looks like
Defining scenes upfront
```typescript
const game = new ex.Engine({
scenes: {
scene1: {
scene: scene1,
transitions: {
out: new ex.FadeInOut({duration: 1000, direction: 'out', color: ex.Color.Black}),
in: new ex.FadeInOut({duration: 1000, direction: 'in'})
}
},
scene2: {
scene: scene2,
loader: ex.DefaultLoader, // Constructor only option!
transitions: {
out: new ex.FadeInOut({duration: 1000, direction: 'out'}),
in: new ex.FadeInOut({duration: 1000, direction: 'in', color: ex.Color.Black })
}
},
scene3: ex.Scene // Constructor only option!
}
})
game.start('scene1',
{
inTransition: new ex.FadeInOut({duration: 500, direction: 'in', color: ex.Color.ExcaliburBlue})
loader: boot,
});
```
