[Service] Expose app id related APIs to public and add getCallerAppId

This exposes getServiceId and getPackageId APIs to puglic profile.

Also, this newly adds getCallerAppId for the use of service apps.
For instance, it can be used when a service app wants to make
a messageport connection with a caller web app.

If there's no caller app, it returns ''.
