Bug 1680995 - Profiler gtests: JSONOutputCheck now parses profile JSON and its properties - r=canaltinova
JSONOutputCheck used to only check the profile output for the presence of some strings. Now it parses the output as JSON, and navigates the JSON data to check expected properties, including their types, and values as needed. Differential Revision: https://phabricator.services.mozilla.com/D98890
