Zitan Chen 6a243b3ade Generalize BackupEngine naming option for share_files_with_checksum SSTs and revert BackupEngine::VerifyBackup to check only file sizes by default (#7032) ... Summary: `bool BackupableDBOptions::new_naming_for_backup_files` is updated to `BackupTableNameOption BackupableDBOptions::share_files_with_checksum_naming`, where `BackupTableNameOption` is an `enum` type with two enumerators `kChecksumAndFileSize` and `kChecksumAndFileSize`. This opens up possibilities of extenting the current naming scheme for backup table files. By default, `BackupTableNameOption BackupableDBOptions::share_files_with_checksum_naming` is set to `kChecksumAndDbSessionId`. Revert `BackupEngine::VerifyBackup` to only check file sizes by default. Also fix the construction of the `SstFileDumper` in `GetFileDbIdentities` by setting a proper `Env` of the `Options` passed in the constructor.
