UefiCpuPkg: Simplify the struct definition of CPU_EXCEPTION_INIT_DATA

Browse Source 
CPU_EXCEPTION_INIT_DATA is now an internal implementation of
CpuExceptionHandlerLib. Union can be removed since Ia32 and X64 have the
same definition. Also, two fields (Revision and InitDefaultHandlers)are
useless, can be removed.
