[tmancey]

Refactor supported regions, large anonymity country codes and other country codes to use std::set for:

Change const std::map<int, std::vector<std::string>> kSupportedRegionsSchemas to const std::map<int, std::set<std::string>> kSupportedRegionsSchemas

Change const std::map<std::string, bool> kLargeAnonymityCountryCodes to const std::set<std::string> kLargeAnonymityCountryCodes

Change const std::map<std::string, bool> kOtherCountryCodes to const std::set<std::string> kOtherCountryCodes
