Temporarily add back rjsmin.py for Chrome OS
Temporarily add back rjsmin.py for Chrome OS

Chrome OS is accidentally relying on DevTools build scripts:
https://source.chromium.org/chromium/chromium/src/+/main:chrome/browser/resources/chromeos/accessibility/common/run_jsbundler.gni;l=16;drc=e86ab6e79b3cef0b3a37f691d8ec38d25fa0ca9e
We should clean that up, but for now let's add back the rjsmin.py script
back to unblock the DevTools autoroller.
