Use Graph to determine DAM availability based on cmp_Asset type

[TRomesh]

This PR to check if we can use meta data query to check if we have cmp_Asset available in graph. Which should indicate that CMP DAM is enabled in a particular instance.

• This simplifies the steps developers have to do when using dam assets in the sdk. With this methods we dont have to pass the attribute damEnabled to the GraphClient.

  const client = new GraphClient(process.env.OPTIMIZELY_GRAPH_SINGLE_KEY!, {
    graphUrl: process.env.OPTIMIZELY_GRAPH_GATEWAY,
    damEnabled: true // not needed since we know if DAM is enabled from the meta data call just before we generate fragments
  });

Pull request overview

This PR refactors the GraphClient to automatically detect Digital Asset Management (DAM) availability by querying the GraphQL schema for the cmp_Asset type, eliminating the need for developers to manually specify a damEnabled option when constructing the client.

Key Changes:

• Removes the damEnabled property from GraphOptions and the GraphClient class
• Adds GraphQL introspection query for cmp_Asset type in the metadata query
• Refactors getContentType() to getContentMetaData() which now returns both content type name and DAM availability status
• Updates getContentByPath() and getPreviewContent() to use the dynamically determined DAM status
