Subject: [PATCH v2 1/1] UefiPayloadPkg: Skip ModuleInfo HOB in Payload

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3754

1. DxeCore will use ModuleInfo to install LoadedImage protocol for DxeCore.
2. DxeIpl will create the ModuleInfo of UniversalPayload. and
   UniversalPayload will create the ModuleInfo of DxeCore.
3. UniversalPayload should skip the ModuleInfo from the DxeIpl to avoid
   the mismatched ModuleInfo for DxeCore.

Changes:
1. Use function IsHobNeed to check if the HOB should be added 2. Add the ModuleInfo check logic in IsHobNeed function
