MdeModulePkg/EbcDxe: prepare support for EBC Debugger

Browse Source 
* This patch introduces EbcDebuggerHook.c/h and inserts the required
  EBCDebugger references into the existing EBC source files.
* With all the hooks defined to their empty version in EbcDebuggerHook.c
  the existing EBC VM behaviour is left unaffected.
