Update dx from android tools

Created by: kageiit

This updates dx to the code drop from android gradle plugin 2.2.0 located at

https://android.googlesource.com/platform/tools/base/+/gradle_2.2.0/build-system/builder/src/main/java/com/android

This version of dx has been modified by the android tools team to be able to run multiple invocations in process. Only slight modifications were made to keep the existing FB added functionality still intact like computeReferencedResources.

There might be some areas that we still want to keep from before for perf, but during profiling, the performance of dx is almost identical compared to the existing fork.
