Each conversion required defining a separate mutator, which will each operate on _all_ modules and requires each to repeat checks whether the mutator should operator. Instead, we introduce a single mutator and modules can define a ConvertWithBp2build to implement bp2build conversion for that module. Test: bp2build.sh Bug: 183079158 Change-Id: I99d4b51f441c2903879092c5b56313d606d4338d
