Adds a new version of the RecordSettingChange function that takes a
mojom::Setting and the value of the setting change. Marks the old
function for deprecation and uses the new function in the user action
tracker. Adds in a top level metric to record which settings were
changed. Also adds in metrics for the Files Page.
