Adds the ability to bind to inputs on dynamically-created components, either by targeting the component itself or one of its directives. The new API looks as follows:
```ts
const value = signal(123);
createComponent(MyComp, {
// Bind the value `'hello'` to `someInput` of `MyComp`.
bindings: [inputBinding('someInput', () => 'hello')],
directives: [{
type: MyDir,
// Bind the `value` signal to the `otherInput` of `MyDir`.
bindings: [inputBinding('otherInput', value)]
}]
});
```
This behavior overlaps with `ComponentRef.setInput`, with a few key differences:
1. `setInput` sets the value on *all* inputs whereas `inputBinding` only targets the specified directive and its host directives. This makes it easier to know which directive you're targeting.
2. `inputBinding` is executed as if it's in a template, making it consistent with how bindings behave for selector-matched components, whereas `setInput` executes outside the lifecycle of the component.
3. It resolves a long-standing issue with `setInput` where it wasn't possible to set the initial value of an input before the first change detection run.
Currently `inputBinding` is used only for `createComponent`, `ViewContainerRef.createComponent` and `ComponentFactory.create`, however it is going to be base for more APIs in the future.
