1687459 - [meta] Enable all resource watchers on the server, for all target types

Status: NEW

(DevTools :: Framework, task)

Description

[Alexandre Poirot [:ochameau]]

The Watcher actor contains a trait, which reports which resource is supported by the current watcher. The current watcher is bound to a given descriptor. So it can be bound to one tab, one webextension or everything (for the browser toolbox).

These traits are defined here:
https://searchfox.org/mozilla-central/rev/c54c71ecbd9e64cafc0df3b596e206ac4072cb91/devtools/server/actors/watcher.js#119-155
Today, most of them are set only for tab debugging. So only for regular toolbox debugging a tab. And typically not for the browser toolbox, or worker toolboxes.

We should enable the resource watchers on the server for all toolboxes,
so that we can get rid of:

• legacy listeners on the client side, which is still used for watcher retporting false traits,
• legacy server code, like WebConsoleActor.startListeners, ThreadActor.sources, ... which have been replaced by ResourceWatcher.watchResources API.
