* Consolidate the two shouldCreateSourceAbiDump() in cc/cc.go and
cc/library.go into cc/sabi.go.
* Rename SAbiProperties.CreateSAbiDumps to ShouldCreateSourceAbiDump.
* sabiDepsMutator determines whether a library needs to generate ABI
dump, and mark their ShouldCreateSourceAbiDump property.
* After this change, sabi.Properties.ShouldCreateSourceAbiDump is the
single source of truth of whether ABI dump should be created or not.
GenerateAndroidBuildActions() should check the property, or call the
property accessor (*sabi).shouldCreateSourceAbiDump().
* classifySourceAbiDump() is no longer a *libraryDecorator receiver.
Instead it uses the libraryInterface object in the
ctx.Module().(*cc.Module).library field. This way
classifySourceAbiDump() doesn't need to depend on the internal fields
of libraryDecorator.
