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]
