Aconfig file dependencies are module-independent, and properly part of
ModuleBase.
Bug: b/308625757
Test: manual
Change-Id: I38c5907d1671cc69bb198345201316ae781fdc9f
Passing the list of all transitive aconfig files to Make causes extra
Kati analysis runs when dependencies are changed in Android.bp files.
Since Make is going to merge them anyways, merge them per-module and
pass a single aconfig file to Make for each module.
