Bug 1814798 - pt 2. Add a PHCManager component to control PHC r=glandium
(deleted), text/x-phabricator-request
Details

We'd like to enable PHC via a pref so that it can eventually be configured via Normandy and/or run on the Release channel. That also means being able to enable PHC late - after prefs have been read.

We could also let the parent process read the prefs and set environment variables for the child processes so they could enable it earlier.

Add the ability to enable and disable PHC at runtime through the malloc
bridge.

Add a new pref for controlling PHC. The pref can be changed at runtime and
will affect the parent and content processes.

Depends on D178754
