scmutil: add writereporequirements() and route requires writing through it
In upcoming patches, to implement Share Safe plan we will be introducing
requires file in store. We need to route all callers to a single function
to check for a share-safe requirement and if present, write requirements to
.hg/store/requires instead.
After this patch, callers directly calling scmutil.writerequires() are only
those where we don't have the repo object, for example when initializing
the repository object itself.
