Lendacky, Thomas 32928415e3 UefiCpuPkg/CpuExceptionHandler: Add missing comma to exception name array
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3373

An update to expand the mExceptionNameStr array failed to add a comma
after original last entry, therefore causing the #CP name to have extra
incorrect characters and the remaining entries to be indexed incorrectly
(off by 1).

Add a comma after the "#CP" entry to resolve this issue.

Tom Lendacky 5277540e37 UefiCpuPkg/CpuExceptionHandler: Add base support for the #VC exception
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

Add base support to handle #VC exceptions. Update the common exception
handlers to invoke the VmgExitHandleVc () function of the VmgExitLib
library when a #VC is encountered. A non-zero return code will propagate
to the targeted exception handler.

Under SEV-ES, a DR7 read or write intercept generates a #VC exception.
To avoid exception recursion, a #VC exception will not try to read and
push the actual debug registers into the EFI_SYSTEM_CONTEXT_X64 struct
and instead push zeroes. The #VC exception handler does not make use of
the debug registers from the saved context and the exception processing
exit code does not attempt to restore the debug register values.

Star Zeng bb207f6cda UefiCpuPkg CpuExceptionHandlerLib: Enhance DumpModuleImageInfo()
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.
