Assign API level 24 to single-source RS API

Updated the RenderScript API spec files, and reran the auto-generating
script for the single-source RS API.

Also updated LatencyBenchmark makefile to set its target-api to 23,
since it uses the deprecated rsForEach() function that takes a script
parameter.
