Move Extension-Controlled Preference functions from ExtPrefs to PreferenceAPI

Move [Set|Remove]ExtensionControlledPref and [Can|Does]ExtensionControlPref
functions from ExtensionPrefs to PreferenceAPI, since these functions were only
ever used in APIs.

This required restructing the ExtensionPrefs unittests slightly, so that derived
testing classes (tests for ExtensionSorting) don't inherit controlled pref
methods, and the functions are isolated in APIs.
