[TCGC][Feature gap] SdkPackage misses information for whether generate convenient/protocol method

[haolingdong-msft]

Issue background

Previously TCGC has helper functions like shouldGenerateConvenient to check whether generate convenient method, similar as protocol method. Majorly the helper function will check @convenientApi and @protocolApi decorators.

export function shouldGenerateProtocol(context: TCGCContext, entity: Operation): boolean {
  const value = getScopedDecoratorData(context, protocolAPIKey, entity);
  return value ?? Boolean(context.generateProtocolMethods);
}

export function shouldGenerateConvenient(context: TCGCContext, entity: Operation): boolean {
  const value = getScopedDecoratorData(context, convenientAPIKey, entity);
  return value ?? Boolean(context.generateConvenienceMethods);
}

Code

But when switching to using sdkPackage, there is no flag to indicate whether to generate convenient/protocol API.

Solution

I think we could add two flags shouldGenerateConvenient and shouldGenerateProtocol under SdkServiceMethod in TCGC.
