Fix TrigT1[RPC|TGC]RecRoiTool configuration to produce self-contained CA
Change TrigT1MuonRecRoiTool.TrigT1MuonRecRoiToolConfig into a proper ComponentAccumulator (CA) configuration module which provides functions returning self-contained CA instead of standalone tool instances which rely on external configuration to be called to work.
Adapt all clients to the change, which required a few other functions to be changed from returning a tool/alg instance into returning a CA.
