[ion] 25836: - Fix KiDebugService to load EDX from KTRAP_FRAME_EDX, not KTRAP_FRAME_EAX!. - Fix CommonDispatchException to check for the argument count in ECX, not EAX. Previously we were ignoring parameter counts and never filling out exception records! - Fix DebugPrint to be the same in user-mode and kernel-mode by using DebugService. This now works because the bugs above were fixed.

Log:
- Fix KiDebugService to load EDX from KTRAP_FRAME_EDX, not KTRAP_FRAME_EAX!.
- Fix CommonDispatchException to check for the argument count in ECX, not EAX. Previously
we were ignoring parameter counts and never filling out exception records!
- Fix DebugPrint to be the same in user-mode and kernel-mode by using DebugService. This
now works because the bugs above were fixed.
