MdeModulePkg/EbcDxe: prepare support for EBC Debugger

* 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.

+/** @file
+  Contains the empty version of the EBC Debugger hooks, to be used when
+  compiling the regular EBC VM module.
+  As debugging is not needed for the standard EBC VM, all calls are left empty.
+
+  The EBC Debugger defines its own version for these calls in EbdHooks.c.
