CLDR-17897 Fix unstable scripts when running GenerateLikelySubtags and ConvertLanguageData

CLDR-17897

While we are improving the population data and likely subtags we are generating side-effects from partial data. This adds new scripts so we can avoid these side-effects in future changes. Ultimately we will want to remove how many overrides are here but it's good to fix this.

See the data updated in this diagram:

• [ ] This PR completes the ticket. -- I'm submitting this request first to separate the changes
• [x] This PR stabilizes the data so its easier to follow up and fix other overrides.

Run this command to regenerate data: mvn package -DskipTests=true && java -jar tools/cldr-code/target/cldr-code.jar ConvertLanguageData && java -jar tools/cldr-code/target/cldr-code.jar GenerateLikelySubtags

Thanks everyone for the comments! It helped me make a better version of this PR in https://github.com/unicode-org/cldr/pull/4015.

Apologies for making a separate one -- rebasing it to the ddl/v47 branch introduced weird merge artifacts so I just made a new PR.
