DxeMain: Fix the bug that StackGuard is not enabled
Commit e7abb94d1 removed InitializeCpuExceptionHandlersEx
and updated DxeMain to call InitializeCpuExceptionHandlers
for exception setup. But the old behavior that calls *Ex() sets
up the stack guard as well. To match the old behavior,
the patch calls InitializeSeparateExceptionStacks.
