[ios] Use unique identifier to name WebSession storage

Change WebSessionStateCache to use GetUniqueIdentifier() to generate
the file name of the session storage on disk. The migration happens
when the file are loaded by renaming them if they are still using the
old name (derived from GetStableIdentifier).

This change will allow deprecating GetStableIdentifier (the value
will still exist and will still be saved when using the current
serialisation code). Additionally, as the new serialisation code
won't save the GetStableIdentifier, this change allow having the
unchanging file name even if the new serialisation code is disabled
by kill-switch.

Include code to migrate the file to the new naming scheme, and an unit
test checking the migration is happening as expected.

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.
