feat(linter): support bind function case for compatibility with `prom…

…ise/no-return-wrap` (#7232)

part of #4655

### Summary

Logic has been added to handle bind functions, unifying the
implementations of `unicorn/no-useless-promise-resolve-reject` and
`promise/no-return-wrap`.
This enables detection of the following code:

```javascript
foo().then((function() { return Promise.resolve(4) }).bind(this))
```

Merging this PR will allow this rule to pass all test cases of
promise/no-return-wrap without options. Additionally, merging #7274 will
ensure that all test cases are passed.
