share: replace the bookmarks.shared file with an entry on a new "shared" file

cd79fb4d75fd introduced a way to share bookmarks. When a repository share that
shares bookmarks was created, a .hg/bookmarks.shared file was created to mark
the repository share as one that shares its bookmarks.

We have plans to introduce other levels of sharing, including a "full share"
mode. Rather than creating a new ".shared" file for each new thing that we may
want to share It seems better to create a single "shared" file that will list
what is shared for a given shared repository. This should make it much easier
to get a list of everything that is shared by a given shared repository.

The shared file contains a list of shared "items" (such as bookmarks). Each
shared "item" is added as a new line in the file. For now the only possible
entry in the file is "bookmarks".
