Understand segment population differences when exporting Audience Manager segments to Experience Platform

[amuraru]

Issue in ./help/using/integration/integration-aep/aam-aep-audience-sharing.md

Currently, the section explains possible causes for segment populations in the two systems when exporting AEP segments to AAM. A similar section should be added to explain the AAM to AEP segment sharing nuances wrt to segment populations
