Document usage of various URLs for loadDataWithBaseURL navs

There are a lot of URLs involved in loadDataWithBaseURL navigations, and
it's not really clear which URLs are used in various cases. This CL
tries to add more documentation around this, and adds TODOs to resolve
or investigate various potential bugs.

See doc for more details:

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.
