Block Editor Tools: New `TermCheckboxes` component

### Description

We need to create `TermCheckboxes` components from time to time in our projects to mimic the core behavior but for a specific/custom taxonomy.

We have some prior art [here](https://l.alley.dev/4d6a5a7759) and [here](https://l.alley.dev/7f80a7bcca).

### Use Case

A `TermCheckboxes` (or with a similar name) component is created. Ideally, it uses core functionality, not a custom REST API endpoint.

```tsx

```
