是不是可以类似这个pr：（#59398）把下划线和点开头的文件都过滤一下？如果担心影响比较大，可以在broker load的option里加一个开关。

支持一个file Group中指定不同的文件类型后，这里其实不过滤也没有问题了。目前是为了保险起见增加了这个_SUCCESS文件的特殊过滤。

What problem does this PR solve?
Problem Summary:
When performing a Broker Load with wildcards (e.g.,
/*), if the directory contains0-byte metadata files like
_SUCCESS, the FE would incorrectly use the format/compressionof these metadata files (usually PLAIN) to overwrite the shared parameters for the
entire file group. This caused the BE to read compressed data files (like LZO) as
plain text, leading to import failures.
This PR fixes the issue by:
_SUCCESSfiles inBrokerLoadPendingTaskto avoid processingthem as data.
format_typeandcompress_typein eachTFileRangeDescinstead ofthe shared
TFileScanRangeParamsin FE (both legacy and Nereids paths).format_typein BE'sCsvReaderto ensure the correctreader is initialized for each file.
