Revert "Fix missing dependencies with RLZ target."

This reverts commit 22333d92d225b2abdf0a628cb811e438b3e94c88.

Reason for revert: suspected of breakage in 'generate_build_files': https://bugs.chromium.org/p/chromium/issues/detail?id=870827#c3

Original change's description:
> Fix missing dependencies with RLZ target.
> 
> chrome_rlz_tracker_delegate.cc depended on browser_process.h which had transitive dependencies on generated mojoms. But it didn't get the public_deps because the rlz target didn't depend on chrome/browser to avoid circular dependencies. Fold it into chrome/browser to fix this properly.
> 
> This does mean that the one unit test in chrome_rlz_tracker_delegate_unittest.cc
>  will not run on chromium-branded bots anymore. That seems better than having flaky dependencies, since untangling the build dependencies looks like a lot of work.
