Disable field data fetching in DevTools and/or sending URLs to Google when it's enabled

[ShivanKaul]

Description

Chromium allows web developers to configure field data fetching via DevTools > Performance > Next steps > Field data > Set up

You get the following consent screen when you press the Set up button:

This is used to compare local metric performance scores with those experienced by users in the wild (documentation)). However, enabling this feature also sends the URL of every page you visit with DevTools you visit to Google. We should disable this for privacy reasons.

We should also update https://github.com/brave/brave-browser/wiki/Deviations-from-Chromium-(features-we-disable-or-remove).

Steps to reproduce

1. Open DevTools > Performance > Next steps > Field data > Set up
2. See privacy disclosure

Actual result

You see a privacy disclosure and the URL of every page you visit is sent to Google with DevTools open if you confirm.

Expected result

The following things should happen, in decreasing order of preference depending on easy it is:

1. Remove the "sending URLs to Google" part from the consent notice and just disable that, keeping the rest of the feature intact
2. Remove the feature all together. This means no "Field data" in Next steps.
