1495389 - Remove performance front specifics out of toolbox class

Status: RESOLVED FIXED

(DevTools :: Performance Tools (Profiler/Timeline), enhancement, P3)

Description

[Alexandre Poirot [:ochameau]]

Toolbox currently handles performance front instantiation and destruction:
  https://searchfox.org/mozilla-central/source/devtools/client/framework/toolbox.js#3026-3074

Most of this code should be moved to the front class.
The toolbox should only register its event listener and that's it:
  this.performance.on("*", this._onPerformanceFrontEvent);

Moving the initialization code to the front will depend on bug 1495387, while still being able to listen for events will depend on bug 1495386.

Attachment: Bug 1495389 - bring back populateWithRecordings to toolbox; r=ochameau

This returns the old behavior of populating the performanceController with recordings from the
toolbox. This is based on a comment that alex made regarding "console-profile-start" being intrinsic
to the toolbox. This is an optional revision

Attachment: Bug 1495389 - introduce checks for async fronts in target; r=ochameau

This introduces some more logic to how async fronts are managed in the target. At some point this
will need to be ported to protocol.js' marshalling methods
