[FEATURE] Add type pre-condition to selectors and suppression groups

### Your suggestion

Currently, selectors and suppression groups can use:

```yaml
if:
  type: .
  equals: <some_type>
```

However, this is a highly used condition that would benefit from an additional separate precondition.

Adding the new precondition will help reduce complexity for common use cases.
