Merge #7276

7276: Remove map module from la-arena public API r=lnicola a=arzg

It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.

This doesn’t compile for the same reason that #7275 doesn’t:

> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.
