Rework bound attribute parameters (#11954)
> [!IMPORTANT] > This affects the Razor SDK. When the compiler flows to the .NET VMR, this commit will be needed: dotnet/dotnet@cb7d5b4. This change makes a few updates `BoundAttributeParameterDescriptor`: - Remove the `Metadata` property. There were only two bits of metadata stored in the `Metadata` property and both have become properties on `BoundAttributeParameterDescriptor` itself. - Introduce `TypeNameObject` that is similar to `DocumentationObject`. This helps reduce the amount of data that needs to be serialized and deserialized. - Don't serialize the `DisplayName` property. This always has exactly the same format for `BoundAttributeParameterDescriptors`.
