[memories] Add `duplicate_visit_ids` field to `ClusterVisit` struct

To provide better support for tracking duplicate visits, this CL
expands the History type ScoredAnnotatedVisit (used for clusters) to be
ClustersVisit, which has a new vector field of duplicate visit IDs.

This vector is just a list of IDs that are considered duplicates of the
canonical visit.

This will be used to both:
 1. Upgrade the best visit with all properties of the duplicate visits.
 2. Delete all duplicates when deleting the parent "best" visit.

This CL doesn't actually use the new field yet, it's just a simple
field addition and rename CL.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
