Especially when GC is enabled, a valid item of `module->types` needs additional checks before casting to WASMFuncType. Also, avoid overflowing if reftype_map_count is 0. Additionally, correctly set IN_OSS_FUZZ based on CFLAGS_ENV for sanitizer configuration. Update ASan and UBSan messages for clarity in non-oss-fuzz environments.
