Put extraCombinedJars after the compiled jars

extraCombinedJars contains the R.jar generated by
ResourceProcessorBusyBox for apps.  It needs to go before any
static_libs dependencies so that the finalized R values take
precedence over any non-final R values that may have been included
in the dependencies.  Moving after the javac and kotlinc compiled
jars helps minimize differences when turning on use_resource_processor
by default by using the MANIFEST.MF generated by soong_zip instead of
the one generated by ResourceProcessorBusyBox, which contains a
different Created-By field.
