Soong was keeping the compiled resources in the same order as the
input resources, which are sorted lexicographically. Converting the
path names in pathsToAapt2Paths results in a list that is no longer
lexicographically sorted.
Make sorts the inputs to aapt2 link by compiled resource name, so
do the same in Soong.
Bug: 69917341
Test: no change to framework-res.apk when converting to Soong
