Move its ownership to the ChainstateManager class. Next to simplifying usage of the kernel library by no longer requiring manual setup of the cache prior to using validation code, it also slims down the amount of memory allocated by BasicTestingSetup. Use this opportunity to make SignatureCache RAII styled Co-authored-by: Ryan Ofsky <ryan@ofsky.org>
