Better instrumentation, enhanced Postgres helpers and more

Hello from London! The heatwave is finally over and we can get back to 🌧. This is Kir, bringing you the latest Rails updates.
The change makes it much easier to instrument CPU time and object allocations with ActiveSupport::Notifications events.
In some files we recommended using rails, in others bin/rails. The inconsistency is now fixed 🎉

Why prefer rails as the recommended executable? It does all the heavy lifting of dispatching to the app appropriate Rails version, so that's why users don't need to target bin/rails manually.
The PR brings support for Postgres' partitioned tables to create_table helper.
Callbacks like before_save will now raise when they receive unsupported arguments.
