Use a typedef for ExceptionCode in all header files instead of including ExceptionCode.h

Use a typedef for ExceptionCode in all header files instead of including ExceptionCode.h
https://bugs.webkit.org/show_bug.cgi?id=71845

Reviewed by Adam Barth.

Source/WebCore:

Some headers in WebCore include ExceptionCode.h to get the ExceptionCode typedef,
while others provide the typedef themselves. Per Darin, the latter is preferred,
so this patch updates all references, and fixes up .cpp files that
need the include in order to access the enum.
