1740232 - Add telemetry to track privacy.restrict3rdpartystorage.rollout.enabledByDefault preference state

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, task, P1)

Description

[Paul Zühlcke [:pbz]]

We should add telemetry to keep track of whether users opted in or out of TCP in standard mode.

This could be a scalar with 3 states:
0: opted out
1: opted in
2: pref unset (= not part of the experiment)

We can update the scalar from _setDefaultCookieBehavior in BrowserGlue.jsm.

[Tracking Requested - why for this release]:
If possible we'd like to also uplift this telemetry patch into 95 to support our TCP rollout experiment. See meta bug 1731713 for details.
Landing this patch is currently blocked on the telemetry data-review.
