Hi
I have another idea to resolve the MdePkg dependency issue.
We can create a new UiLib in MdeModulePkg with interface such as:
UiLibCreatePopUp().
Then we update all the *caller* to use the new interface. I did a search and
find caller below:
We can add DEPRECATE flag for the UefiLib:CreatePopUp(), to avoid it being used
any more.

Subject: Re: [edk2] [RFC] [MdePkg] UefiLib: CreatePopUp
Hi Felix,
Thanks for your clearly explanation, I misunderstand your changes before. But
I think this change still has small impact because the platforms DSC file need
to include the new UiLib instance.
I think the new UiLib library class need to be added into MdePkg because
UefiLib need to depend on it. This may need get some input from MdePkg
maintainer. If you add this new UiLib, I will add my new API into this library
class.
Thanks,
Eric
