1. DxeIplPeim will locate Vector Handoff Table PPI and build GUIDed HOB if it has.
2. DxeMain will get Vector Handoff Table GUIDed HOB to install configuration table if it has.
3. Updated CPU Exception Handler Library to provide 3 new APIs to replace original one API and updated NULL instance accordingly.
4. Updated DxeMain/CapsuleX64/BootSriptExectorDxe to use the new API in CPU Exception Handler Lib.
