If a widget toggles between displaying two different RenderGlimmer instances, the Widget framework treats them as the same, and so `update()` is called rather than destroy/init. This commit detects this scenario and manually destroys/inits to ensure the correct component is being rendered.
This allows an arbitrary Glimmer template to be rendered inside a Widget. That template can include any kind content, including Classic Ember components and Glimmer components. This leans on Ember's official `{{#in-element}}` helper which means that all component lifecycle hooks are called correctly.
This is a modern replacement for our existing `ComponentConnector` implementation. We'll deprecate `ComponentConnector` in the near future.
Example usage:
```javascript
// (inside an existing widget)
html(){
return [
new RenderGlimmer(
this,
"div.my-wrapper-class",
hbs`<MyComponent @arg1={{@data.arg1}} />`,
{
arg1: "some argument value"
}
),
]
}
```
See `widgets/render-glimmer.js` for documentation, and `render-glimmer-test` for more example uses.
