New Rule: `no-simple-alias`

A new rule disallowing `oneWay` `reads` and `readOnly` off of another prop on the same context.

```js
import Component from '@glimmer/component';
import { oneWay, reads, readOnly } from '@ember/object/computed';

export default MyComponent extends Component {
aProp = true;

// BAD
@oneWay('aProp') oneWayProp;
@reads('aProp') readsProp;
@readOnly('aProp') readOnlyProp;

// OK
@oneWay('args.aProp') oneWayProp;
@reads('args.aProp') readsProp;
@readOnly('args.aProp') readOnlyProp;
}
```
