Instrumented libraries: Remove dependence on GYP_DEFINES
This CL ports download_binaries.py and unpack_binaries.py from using
GYP_DEFINES to gn args. Previously, there was a gotcha step where you
had to run 'gclient sync' with the right GYP_DEFINES to actually download
the prebuilt instrumented libraries. This CL removes that step.
