Months ago, I sent patch set to fix potential issues in the usage of SMI handler unregistering SMI handler. Discussion can be found in below link: https://edk2.groups.io/g/devel/topic/103925794#114251
The conclusion was to only support SMI handler unregistering itself, and not allow SMI handler unregistering other handlers, because we thought there would be no such usage. However, recently, I find in some platform, there is kind of usage. To also support SMI handler unregistering other handlers, this patch set use a totally different design. So I revert the former ones first to make the code more readable. Thank Laszlo for bring up the initial idea for the new design.
