Use C# 12 features

[keyboardDrummer]

What was changed?

• Use the collection expression feature where possible
• Use the primary constructor feature where possible

How has this been tested?

No additional tests needed, since this is a pure refactoring

Really like the primary constructors! But isn't it technically less safe when you convert a readonly field to a primary constructor parameter, since they're always writeable?

Good point. You can make them readonly by prefixing them with in but that has not been done in this refactoring :/

I've removed that commit now, and did a few manual applications of primary constructors.
