### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
When querying Hive tables stored on HDFS, Doris recursively lists all
files in the table/partition directories. However, HDFS directories often
contain hidden directories (prefixed with `.` or `_`)
such as:
- `.hive-staging_hive_xxx` - Hive staging directories
- `_temporary` - Spark/MapReduce temporary output directories
- `_SUCCESS` markers and related directories
These hidden directories can contain large amounts of temporary files that:
1. Should not be included in query results
2. Cause unnecessary I/O overhead during file listing
3. May slow down query planning significantly for large tables
this commit added a new FE configuration
`enable_list_hdfs_files_ignore_hidden_directory` (default: `true`) that enables
skipping hidden directories during recursive HDFS file listing.
When enabled, the HDFS file listing will use manual directory traversal
instead of Hadoop's native recursive listing, allowing us to skip directories
whose names start with `.` or `_`.
