I think a virtual package ("Provides") might be the right answer here. That is mir-platform-graphics-android8 (and mesa etc) would then "Provide" a virtual "mir-server-graphics-8". And libmirserverN would depend on virtual package "mir-server-graphics-8" that is only supplied by installing one or more driver packages.
