Bug 1673513 - Use ProgressLogger in Gecko Profiler - r=florian
Add `ProgressLogger` parameter to most JSON-generating functions. Each function can update the given `ProgressLogger` between 0% and 100%, and create sub-loggers when calling functions. The main goal of this instrumentation is to notice when any progress is made by child processes (when the parent process is gathering profiles), so it needs to go deep enough so that it is not stuck on a progress value for "too long" -- During development, that meant progress was always happening when observed every 10ms; In later patches, the overall timeout for no-progress-made will be at least 1 second. Differential Revision: https://phabricator.services.mozilla.com/D135479
