- Removes banned_data_types_, PUBLIC identity advertisements will never have any corresponding credentials anyways, so decryption will always be skipped and this is now guarenteed by asserts in UpdatePublicCredentials - Filtering adv based on identity is moved into advertisement Filter which already contains the requested identity info from scan_request - LegacyPresenceScanFilter is no longer used by AdvertisementDecoder since this is not being used anywhere at the moment - Cleanup miscellaneous clang-tidy lints about missing or unused includes PiperOrigin-RevId: 620086399
