Remove temporary conversions and clean up.

[Final NIK -> NAK conversion CL]

This CL removes the implicit conversion from NAK -> NIK that's allowed
for a quick transition between classes in the network state. It also
removes the temporary convertor from NIK->NAK that cannot be used in
a partitioned network stack since the NAK may be less granular than the
NIK.

Once the temporary convertors are disabled this CL fills in the NIK->NAK
replacements already completed.

At a high level the NAK should partition the network service while
ensuring the HTTP cache always has access to a valid NIK. Since a
NAK->NIK conversion is invalid any path that partitions the cache needs
to keep the NIK.

NetworkAnonymizationKey is an experimental key that will keep track of
the top_frame_site, the frame_site, an optional nonce and a bool
indicating if the frame_site is cross site from the top_frame_site.
These properties will be used to experiment with different partition key
schemes for the network stack while leaving the HTTP cache layer
triple-key partitioned by the NetworkIsolationKey.

More information on origin of this key can be found here:

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.
