[ads] Should not fetch geo and catalog on iOS when Brave Rewards/News disabled

[aseren]

Description

Following Brave News chromium preferences are always set to true because iOS uses it's own set of native preferences:

brave_news::prefs::kBraveNewsOptedIn
brave_news::prefs::kNewTabPageShowToday

https://github.com/brave/brave-core/blob/master/ios/browser/api/ads/brave_ads.mm#L1531

This was working as expected until ShouldAlwaysRunBraveAdsService feature is enabled for iOS where we start brave ads when rewards and news are disabled. To fix the issue we need to properly set Brave News chromium preferences basing on Brave News native preference values for iOS.

Following preferences should be also properly set:

ntp_background_images::prefs::kNewTabPageShowBackgroundImage
ntp_background_images::prefs::kNewTabPageShowSponsoredImagesBackgroundImage

These settings will be properly handled within the issue: #39658

ntp_background_images::prefs::kNewTabPageShowBackgroundImage
ntp_background_images::prefs::kNewTabPageShowSponsoredImagesBackgroundImage

The above requires 1.68.122 or higher for 1.68.x verification 👍
