Alexandre Poirot 599be925bc Bug 1770363 - [devtools] Implement on-demand multiprocess debugging in TargetCommand API. r=nchevobbe
This new feature will only work in the "MBT", when devtools.browsertoolbox.fission is true.

It is based on yet another preference, devtools.browsertoolbox.scope,
which is meant to be toggle by DevTools UI only (see next patches).

When the new pref is set to "everything", we will observe FRAME and PROCESS targets
and so debug everything running in content processes.
But when it is set to "parent-process", we will only observe WORKER
and be restricted to parent process resources only.
