Issue:
Change Request: add a typedef for formatter functions
### ESLint version

v8.10.0

### What problem do you want to solve?

ESLint does not include a type definition for the signature of a formatter function.

A [(custom) formatter](https://eslint.org/docs/developer-guide/working-with-custom-formatters) is a plain function that accepts a list of lint results and an optional second parameter [`context`](https://eslint.org/docs/developer-guide/working-with-custom-formatters#the-context-argument) with properties `cwd` and `rulesMeta`. This would be the expected type of the default export of a formatter module (a [TypeScript example](https://github.com/sindresorhus/eslint-formatter-pretty/blob/decbd28/index.d.ts#L12-L15)).

By contrast, there exists a type [`Formatter`](https://eslint.org/docs/developer-guide/nodejs-api#-formatter-type) which is used for a different purpose: it is the type of a value resolved by `eslint.loadFormatter`. This is an object with a method named `format` that accepts a single argument.

### What do you think is the correct solution?

Adding a type definition for the signature of a formatter function would be useful as a guideline to work with custom formatters and other tools that deal with those formatters, in the same way the type definitions for e.g. `Rule` or `Plugin` help with rules and plugins.

### Participation

- [X] I am willing to submit a pull request for this change.

### Additional comments

I could submit a PR if desired, but I would probably need some input from the team, for example about naming conventions.

<!--
    The following is required for all pull requests:
-->

#### What changes did you make? (Give an overview)

* Add type `FormatterFunction`
* Rename type `Formatter` to `LoadedFormatter`
* Use `FormatterFunction` in the return type of `CLIEngine.getFormatter`
* Move type `LintResult` to shared types because it is referenced by `FormatterFunction`
* Fix a misspelling of `LintResult` in JSDoc
* docs: Update/clarify some text about custom formatters
* ~~docs: Rename variable `formatter` to `loadedFormatter` in code examples~~

#### Is there anything you'd like reviewers to focus on?

<!-- markdownlint-disable-file MD004 -->

I don't think there is a way to test type definitions or any other of the changes listed above at this time, so probably everything needs a careful human review.
