Improve Error Reporting: Multi-line records

# What
Multi-line records can be used with or without ending `;`
However, when you don't use `;`, then the offset indentation leads to mysterious errors.

```fsharp
type Person1 = {
FirstName: string
LastName: string
Height: int
}
```

`error FS0010: Unexpected symbol ':' in type definition. Expected '}' or other token.`

and
```fsharp
type Person2 = {
FirstName: string
LastName: string
Height: int
}

let p = {
FirstName = "John"
LastName = "Doe"
Height = 123
}
```

`error FS0001: This expression was expected to have type string but here has type bool`

# Why

As generally F# doesn't need semicolons in line-endings, it's easy to start with more readable code without semicolons. However if you later have large records and try to refactor the code it's painful to detect the errors.
