Annotation TopSupported should be a Tag, not a Record

[joostverhoog]

TopSupportedConfiguration.ToEdmExpression creates a EdmRecordExpression, but TopSupported is a Core.Tag.

Assemblies affected

OData ModelBuilder

Reproduce steps

1. Have a simple class Students
2. Add an entity set for it that does not have top supported: new ODataConventionModelBuilder().EntitySet<Student>("Students").HasTopSupported().IsTopSupported(false);
3. Inspect the resulting $metadata file

Expected result

The Students entity set has an annotation <Annotation Term="Org.OData.Capabilities.V1.TopSupported" Bool="true" />

Actual result

The Students entity set has an annotation

<Annotation Term="Org.OData.Capabilities.V1.TopSupported">
  <Record>
    <PropertyValue Property="TopSupported" Bool="false"/>
  </Record>
</Annotation>
