[prefs] Store user_selected_types in a pref in local store

This CL tackles a bug in the newly introduced code for always syncing
priority prefs: Priority prefs not marked as always syncing do not
return the account value before sync service is initialized, i.e. before
DualLayerUserPrefStore::OnSyncServiceInitialized() is called. This is
because the user selected sync types are not yet known and we avoid
returning priority pref values if "preference" is not selected by the
user for sync. This bug _might_ affect services which request a priority
pref before this point.

With this CL, the user selected types are preserved from the previous
run in a local-only preference. This allows deciding whether to return
the account priority pref value right away. Any change to the user
selected types will get informed when
DualLayerUserPrefStore::OnSyncServiceInitialized() is called.

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.
