DEV: Introduce a helper for handling events (#25433)

Browse Source 
Instead of

```hbs
{{on "input" (action this.foo value="target.value")}}
{{on "input" (action (mut this.bar) value="target.value")}}
```

you can use:

```hbs
{{on "input" (with-event-value this.foo)}}
{{on "input" (with-event-value (fn (mut this.bar)))}}
```

or in gjs:

```gjs
import { fn } from "@ember/helper";
import { on } from "@ember/modifier";
import withEventValue from "discourse/helpers/with-event-value";
…
{{on "input" (withEventValue (fn (mut this.bar)))}}
```
