This new API only works on DEBUG build. It will search the PE/COFF image base
forward the input address in this PE/COFF image and returns it.

Export DumpCpuCotext() to display CPU Context. We will invoke
PeCoffGetEntrypointLib's PeCoffSerachImageBase() to get PE/COFF image base.
Display exception data bit value for page fault exception.
