Add ExtendedCall to PLCObject as a replacement of RemoteExec and reflect it in eRPC interface.
ExtendedCall is a generic remote procedure call that runtime code can register to and that IDE extensions can call.
For example a fieldbus extension can use ExtendedCall to browse the fieldbus devices connected to the runtime.
