David Peter da8aa6a631 [ty] Support iterating over enums (#19486 )

## Summary

Infer the correct type in a scenario like this:

```py
class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

for color in Color:
    reveal_type(color)  # revealed: Color
```

We should eventually support this out-of-the-box when
https://github.com/astral-sh/ty/issues/501 is implemented. For this
reason, @AlexWaygood would prefer to keep things as they are (we
currently infer `Unknown`, so false positives seem unlikely). But it
seemed relatively easy to support, so I'm opening this for discussion.

## Test Plan

Adapted existing test.

## Ecosystem analysis

```diff
- warning[unused-ignore-comment] rotkehlchen/chain/aggregator.py:591:82: Unused blanket `type: ignore` directive
```

This `unused-ignore-comment` goes away due to a new true positive.
