Use std::shared_ptr in EventSetup interface (L1 and DB)

[wmtan]

The only place that the CMS framework still uses boost::shared_ptr is in the interface to the EventSetup system, where std::shared_ptr is also supported. In order to remove this last vestige of boost::shared_ptr,
users of EventSetup need to be converted to std::shared_ptr. This PR does this for L1 packages, and the necessary changes to DB that the L1 changes require. Also, std::make_shared is implemented where it makes sense, because it simplifies the code and saves a memory allocation.
This PR is totally technical.

@cmsbuild @davidlange6 The unit test fails in the base IB. The failure has nothing to do with this PR.
