Enhance DumpModuleImageInfo() for page fault with I/D set.
If it is page fault with I/D set, the (E/R)IP in SystemContext
could not be used for DumpModuleImageInfo(), instead of, the next
IP of the IP triggering this page fault could be found from stack
by (E/R)SP in SystemContext.
IA32 SDM:
— I/D flag (bit 4).
This flag is 1 if the access causing the page-fault exception was
an instruction fetch. This flag describes the access causing the
page-fault exception, not the access rights specified by paging.
The idea comes from SmiPFHandler () in
UefiCpuPkg/PiSmmCpuDxeSmm/Ia32/PageTbl.c and
UefiCpuPkg/PiSmmCpuDxeSmm/X64/PageTbl.c.

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.
