Fix record definition using Stroustrup style

[sheridanchris]

Adjusted the formatting for record definitions with accessibility modifiers using the Stroustrup style.
This may or may not be a naive approach to solving this problem, any feedback would be much appreciated!
This will fix #2481

I'm not sure what the "correct" format is here. I went with my original example in the issue

type Person = private {
    FirstName: string
    LastName: string
}

Hello, this is a good start!
Please also add an entry in the changelog.
Thanks

The sepNlnWhenWriteBeforeNewlineNotEmpty will not really play out when there is a comment after the access modifier.

Something like:

type Person = private // foo
    {
        FirstName: string
        LastName: string
    }

would be formatted to

type Person = private // foo
{
    FirstName: string
    LastName: string
}

It is better to use sepSpace in this case and let the comment flow after the { like

type Person = private { // foo
    FirstName: string
    LastName: string
}

This isn't super accurate but good enough for now.

Should I add a test case that covers this scenario?

[nojaf]

I would like you to change (sepNlnWhenWriteBeforeNewlineNotEmpty sepSpace) with sepSpace here.

Right, just asking if you'd like me to add an additional test case or not.

[nojaf]

No, it's fine for now. Adding the test case described above wouldn't strictly be correct.
If you have something like private // foo after formatting that part should in theory be preserved. This is now not the case but the output is acceptable, so I would leave it be.

[sheridanchris]

Alright, I've made the requested changes and removed another redundant test case.

Many thanks for this first contribution.
I'll most likely release another beta somewhere tomorrow or over the weekend.
