Convert FwdPtrCollectionFilter to stream filter

[knoepfel]

It did not appear necessary to me to create a stream filter of this type separate from a legacy filter. In other words, the two instantiations of this template looked conducive to being stream filters.

A new Pull Request was created by @knoepfel (Kyle Knoepfel) for CMSSW_9_0_X.

It involves the following packages:

CommonTools/ParticleFlow
CommonTools/UtilAlgos

@rappoccio, @jdolen, @makortel, @ahinzmann, @gkasieczka, @cbernet this is something you requested to watch as well.

• change to edm::stream::EDFilter and also refactored to a shorter and what appears to be equivalent implementation
