Translate C# auto-properties the same as a field

[Jand42]

Currently, C# auto-implemented properties translate to a field with name $PropertyName (independent of Name attribute use), and both getter and setter is added as separate functions.

This is unnecessary bloat, it would be possible to just treat them the same as fields.

Extra concerns that need to be tested:

• Accessing a static auto-property of a static class should still run the static constructor if there is one.
• JSON de/serialization on both client and server, should be compatible and respecting Name attribute.
• Auto-implemented properties that are overrides still translate to separate getter/setter with the inherited names for overriding in JS.

TypedJson.Serialize/Deserialize is currently not compatible between client/server because of this, so I am changing this to a bug. Workaround: convert to regular properties (e.g. with VS's "Convert to full property" lightbulb menu option)
