Enable annotation quoting for multi-line expressions (#9142)
Given:

```python
x: DataFrame[
    int
] = 1
```

We currently wrap the annotation in single quotes, which leads to a
syntax error:

```python
x: "DataFrame[
    int
]" = 1
```

There are a few options for what to suggest for users here... Use triple
quotes:

```python
x: """DataFrame[
    int
]""" = 1
```

Or, use an implicit string concatenation (which may require
parentheses):

```python
x: ("DataFrame["
    "int"
"]") = 1
```

The solution I settled on here is to use the `Generator`, which
effectively means we write it out on a single line, like:

```python
x: "DataFrame[int]" = 1
```

It's kind of the "least opinionated" solution, but it does mean we'll
expand to a very long line in some cases.
