Add auto tiles by config

Added a new config resource that allows to list a set of secure secure
settings paired with a tile spec (including custom). When that setting
toggles to a non-zero value for the first time, the tile will be auto
added.

Also removed previous code for config_extraQuickSettingsTiles

Test: manual (inversion)
