Update search engine defaults for BR / AR

Description

Update search engine defaults for:

• Brazil (BR)
• Argentina (AR)

Brave should be at the top of drop down list at brave://settings/search

Related: https://github.com/brave/brave-browser/issues/18331 and https://github.com/brave/brave-browser/issues/23814

Test plan

Region set to BR / AR

1. Fresh profile
2. Search onboarding should NOT be shown
3. Default search engine SHOULD be Brave
4. Visit brave://settings/searchEngines
5. Brave SHOULD be first in the Default search engines list

Region set to anything else (excluding CA / DE / FR / GB / US / AT / ES / MX)

1. Fresh profile
2. Search onboarding SHOULD be shown
3. Default will NOT be Brave Search
4. Visit brave://settings/searchEngines
5. Brave SHOULD be first in the Default search engines list - unless you’re in a region where Yandex is default (AM, AZ, BY, KG, KZ, MD, RU, TJ, TM, UZ). In that case it will be second.

This issue was closed incorrectly as the work on Android was not completed.

Reopening, adding the correct Android project and assigning to @deeppandya & @timchilds

This particular PR can be verified on Android as well but the onboarding portion will be done via https://github.com/brave/brave-browser/issues/26318 as per https://github.com/brave/brave-browser/issues/26318#issuecomment-1299587680. @brave/qa-team when verifying the above, you can use the STR/Cases outlined via https://github.com/brave/brave-core/pull/15669#issuecomment-1299023358 & https://github.com/brave/brave-core/pull/15669#issuecomment-1299634053. However, rather than going through all the cases I did, each platform should:

• pick either BR or AR (the new ones added)
• pick one of the previous locales that have Brave as default (CA / DE / FR / GB / US / AT / ES / MX)
• pick a locale that doesn’t have Brave as the default SE (example: Japan or Poland)
• pick a locale that has Yandex set as the default SE
