Browsing Data Model: Ensure MediaLicense access is reported correctly

The KeySystemConfigSelector was checking whether kLocalStorage access
was available to determine whether key access was allowed. This
resulted in an access report to local storage being ultimately
received by the PageSpecificContentSettings.

Media Licenses are a Quota managed type, and so to be correctly
represented in the in-context UI (and correctly deleted) they should
be reported as such.

This CL changes the KeySystemConfigSelector to check for IndexedDB
access instead, which ultimately presents as an access to quota
managed storage, and so license information will be deleted
correctly.

CL also introduces a debugging string into the BrowsingDataModel
test util to make determining the difference between expected and
actual entries simpler to debug.

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.
