Remove support for multi-line error messages in static error tests.

The static error test format allows an expected error message to contain newlines like:

```dart
some bad code;
// [cfe] The error message
// is two lines long.
```

Here, the expected error is "The error message\nistwo lines long."

This has an unfortunate side effect in that if you have a comment
immediately after a static error expectation, it will be treated as part
of the expected error:

```dart
some bad code;
// [cfe] Error.
// Unrelated comment.
```

This will expect the CFE to report "Error.\nUnrelated comment."

I looked at every static error test and there are no intentional uses
of multi-line expectations. The only two I found were both bugs.

Since this functionality is unused and error-prone, this CL removes it.
Error expectations can only be one line.

Fix #60137.
