convert TriggerResultsFilterFromDB from an HLTFilter into a simpler edm::EDFilter
work in progress: convert all hltFilters to global modules
turn FTSFromVertexToPointFactory::operator() into a static method

FTSFromVertexToPointFactory does not have any data members, and a single (currently non-const) method, FTSFromVertexToPointFactory::operator() .
This patch changes that single method into a static method, FTSFromVertexToPointFactory::get(), and propagates the change to downstream code.
work in progress: convert all hltFilters to global modules
remove unnecessary EventSetup caching
