Background task mode is roughly equivalent to `xpcshell`, but inside the regular browser startup flow. There is no browser window (no `Window` at all) and there should be no content processes. It's sufficient to treat it like `xpcshell`, with its own stripped-down actor and a few tweaks to the integration points. The structural changes in this commit keep `--backgroundtask` mode slim in the regular case when the Devtools are *not* requested. This is reflected in the small changes needed to the `browser_xpcom_graph_wait.js` test: loading the Devtools unconditionally causes a huge amount of code to be loaded. In order to load the Devtools framework conditionally, we check for Devtools-specific command line flags and delegate to Devtools when appropriate. In order to check the command line flags, we turn the `BackgroundTasksManager` into an XPCOM service, which allows it to be instantiated by XPCOM in order to handle the command line. One final note: this leaves two XPCOM components, "backgroundtasks" and "backgroundtasksmanager". Why not combine them? This is technically possible but not attractive: we really do want a natural place for native/C++ code ("backgroundtasks") and JavaScript code ("backgroundtasksmanager").
