[patch v2 0/5] Unload image on EFI_SECURITY_VIOLATION

["Dandan Bi" <dandan.bi@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1992

v2:
(1) Just separate the patch in MdeModulePkg into module level, the changes in EmbeddedPkg and ShellPkg are the same with V1.
(2) Drop the update in PciBusDxe module in MdeModulePkg since with EFI_SECURITY_VIOLATION returned, the image may be used later.


For the LoadImage() boot service, with EFI_SECURITY_VIOLATION retval,
the Image was loaded and an ImageHandle was created with a valid
EFI_LOADED_IMAGE_PROTOCOL, but the image can not be started right now.
This follows UEFI Spec.

But if the caller of LoadImage() doesn't have the option to defer
the execution of an image, we can not treat EFI_SECURITY_VIOLATION
like any other LoadImage() error, we should unload image for the
EFI_SECURITY_VIOLATION to avoid resource leak.

This patch is to do error handling for EFI_SECURITY_VIOLATION explicitly
for the callers in edk2 which don't have the policy to defer the
execution of the image.
