[iOS] Include server-based AI infrastructure in default binary

Previously, all our AI infrastructure was gated behind the internal
optimization guide build flag, since the library was increasing our
binary size by ~30mb. However, the server-based inference code does not
impact binary size, and could therefore be included in the binary
without introducing this regression.

This CL moves the server-based infrastructure behind a system flag
(experimental setting), which will allow for most of the AI prototyping
menu to be shared internally without affecting the binary. This also
unblocks AI feature development using server inference, as that part of
the infrastructure is no longer guarded by a build flag.

Also adds adamta@ as iOS optimization guide owner to reduce review
friction moving forward.

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.
