Add performance warnings to Deprecated module.
Adds a dedicated handler for performance warnings to be logged to consoles if known performance-impacting methods are called. Search service init is changed from a deprecation warning to a performance warning for synchronous init. This also re-enables the warning for the Basilisk & Co. search service initialization which was previously removed in [a930a79] See also the discussion on #916.
