Add bindQueriesToElement to remove need for duplicated code in libraries built on dom-testing-library

There's a block of code used by vue-testing-library, react-testing-library and in the tests here:

```javascript
   const containerHelpers = Object.entries(queries).reduce(
    (helpers, [key, fn]) => {
      helpers[key] = fn.bind(null, element)      
      return helpers
    },
    {},
  )
```

I propose adding a `bindQueriesToElement` utility function to encapsulate this code.
