build: bump zstd submodule Updated third_party/zstd submodule from pre-v1.5.5 to v1.5.5 version. The new version fixes a rare corruption bug in high compression mode. While the probability might be very small, corruption issues are nonetheless very serious, so an update to this version is highly recommended, especially if you employ high compression modes (levels 16+). See full changelog in [1]. 1. https://github.com/facebook/zstd/releases/tag/v1.5.5 Fixes #8537 Follows up #8391 NO_DOC=build NO_TEST=build

test/fuzz: get rid of custom cflags We manage using sanitizers with CMake flags: ENABLE_ASAN and ENABLE_UB_SANITIZER. sql_fuzzer enables Address Sanitizer by passing -fsanitize=address directly to CFLAGS. It works fine on OSS Fuzz, but breaks building fuzzers for Sydr [1], because Sydr requires building with disabled sanitizers, see documentation [2]. 1. https://github.com/ispras/oss-sydr-fuzz/pull/164 2. https://sydr-fuzz.github.io/docs/#%D0%BE%D0%B1%D0%B5%D1%80%D1%82%D0%BA%D0%B0-sydr Fixes #8529 NO_CHANGELOG=<fuzzing testing> NO_DOC=<fuzzing testing> NO_TEST=<fuzzing testing>
