Ruiyu Ni e048823f57 MdeModulePkg/SecurityStubDxe: Report failure if image is load earlier
The 3rd party image should be loaded after EndOfDxe event signal and
DxeSmmReadyToLock protocol installation. But non-SMM platform doesn't
published DxeSmmReadyToLock protocol.
So the SecurityStubDxe can only depend on EndOfDxe event.

This patch enhances the SecurityStubDxe to listen on
DxeSmmReadyToLock protocol installation and if any 3rd party image
is loaded before DxeSmmReadyToLock, it reports failure.

Ruiyu Ni 8be37a5cee MdeModulePkg/SecurityStubDxe: Defer 3rd party image before EndOfDxe
The images not from FV are treated as 3rd party images. They will
be deferred to dispatch when they are dispatched before EndOfDxe
event.
It's a new feature in the BS.LoadImage() path which can disallow
executing 3rd party images before EndOfDxe and re-execute them
after EndOfDxe (through EfiBootManagerDispatchDeferredImages
introduced in next commit).
