MdeModulePkg/EbcDxe: add EBC Debugger configuration application

* Introduce a generic Debugger Configuration protocol.
* Add private configuration data in the EBC Debugger and make it
  register the Debugger Configuration protocol on initialization.
* Add a shell application that uses the protocol above to access
  the private data in order to configure the EBC debugger.
