docs: Add naming conventions for certain things.

This isn’t supposed to be too prescriptive.  The C++ stuff just codifies
some things we’ve managed to mostly agree on for public interfaces.  The
stuff for titles/descriptions is also just codifying existing rules so
there’s something to point people towards.  This will need to be refined
as we go forward.
