Make ListBox filter directly overridable

### Provide a general summary of the feature here

It would be nice if the filtering [here](https://github.com/adobe/react-spectrum/blob/b0118e99853f9785e930fbc3e01f47ce5c43ff79/packages/react-aria-components/src/ListBox.tsx#L121) could be override directly on the `ListBox` declaratively. Like

```tsx
// No filtering at all

// Custom filter
customFilter(item, input)} />
```

Right now, to achieve custom filtering, you need to setup the combox as a controlled component: https://react-spectrum.adobe.com/react-aria/useComboBox.html#custom-filtering

And then repeat the items you want in the context on both the Listbox and Combox. This introduces local state where you don't _need_ to have it.

I'd be happy to make the PR if the team is okay with it

Alternatively, I can also see a solution where the `filter` is overridable on Combobox itself.

```ts
customFilter(item, input)} />
```

Another solution that I would enjoy seeing, would be enabling this pattern:

```tsx
// Inside Combobox > Listbox > ListboxSection >

contains(o.value, use(ComboBoxStateContext)?.inputValue ?? '') ||
contains(o.label, use(ComboBoxStateContext)?.inputValue ?? ''),
)}

```

This work require being able to simply toggle the filtering on/off.

### 🤔 Expected Behavior?

Custom filtering on Comboboxes should not require local state

### 😯 Current Behavior

Custom filtering on Comboboxes requires local state

### 💁 Possible Solution

All a `filter` prop on `Listbox` OR on components that provide the filter currently (e.g. `Combobox`)

### 🔦 Context

I had to introduce local state because I wanted the filtering to react to the aria-label _and_ some invisible metadata. I felt as though I was breaking a pattern by introducing local state.

Start at packages/react-aria-components/src/ListBox.tsx around the linked filtering logic, then compare it with the useComboBox custom-filtering guidance. Resolve whether filtering belongs on ListBox, Combobox, or Collection, and confirm that the chosen API supports disabling or customizing filtering without controlled local state.
