Optimize hot spots in Stream Manager (#3322) * Replace std::unordered_map with tsl::hopscotch_map in tuple-cache.h * Replaced std::hash with a faster xxhash implementation to speedup the topology if it uses fields-grouping strategy * Enabled O3 optimization level be default to guarantee all smart pointers are inlined * xxhash migration has been rollbacked since its performance effect is negligible * RETRY_ATTEMPTS bumped to 50 since Travis is slow
