Bug 1425909 - Enable adding scalars in artifact builds without rebuilding Firefox. r=chutten,froydnj
This patch enables generating a JSON file that mirrors the scalar definitions in Scalars.yaml. On local developer builds, this file is loaded when Firefox starts to register all the scalars. If some change was introduced in the definition files, the new scalar will be dynamically added. The JSON definition file will be regenerated every time an artifact build is performed or the build faster command is invoked.
