Fixed forward decls in AlignmentGlobalTrackSelector.h

[Teemperor]

The Event forward decl goes into the edm namespace and the Track
forward decl in the reco namespace. Also added the missing
forward decl to EventSetup to make this header parsable on its own.

[Teemperor]

Part of the work going on regarding the C++ modules migration of CMSSW (tracked as issue #15248). This PR is not meant to refactor things, but just to make these headers compile.
