Subject: [ast] Improve precision of Ast location recognition in serialization.

We follow the suggestions in #402 and turn uses of `Loc.located` in
`vernac` into `CAst.t`. The impact should be low as this change mostly
affects top-level vernaculars.

With this change, we are even closer to automatically map a text
document to its AST in a programmatic way.
