Before getting rid of GetRootTranslationTableInfo() and the related LookupAddresstoRootTable() in AARCH64's version of ArmMmuLib, add a version of the former to CpuDxe, which will be its only remaining user. While at it, simplify it a bit, since in the CpuDxe cases, both OUT arguments are always provided. Note that this removes the declaration of GetRootTranslationTableInfo() as well, but this is a declaration that is private to CpuDxe, and it really doesn't belong here in the first place. Since ArmMmuLib's version of GetRootTranslationTableInfo() is going to be replaced shortly anyway, don't bother moving this .h declaration elsewhere.
