route: rename Map to NameMap

The `Map` type is renamed to `NameMap` to better reflect what it does.

`createFromAdjLsdb` and `createFromCoordinateLsdb` functions are changed
to static functions, to match how they are used in callsites.

Unnecessary shared_ptr usage in `createFromAdjLsdb` is eliminated.

Doxygen of `NameMap` is added or improved.
