Improve support for anonymous records

Anonymous records are not currently well-supported.

```delphi
const
A: record
B: Boolean;
C: Boolean;
end = (B: True; C: False);
```
This example is formatted correctly. Additionally, each physical line corresponds to a `LogicalLine` produced by the parser.

In almost every case, the formatting produced with an anonymous record is undesirable and inconsistent with the established style.
