add a tool api to verify the consistency of the file cache, checking whether
the disk cache is under the control of the file cache management system
### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #41280
Problem Summary:
Occasionally, we found that there have been cases of disk cache data
escaping from the management of Doris file cache, causing disk space leaks. To
make it easier for debugging, we need a checking tool that compares the
contents in the Doris file cache memory management structure with the current
disk contents to identify the differences between the two (which are potential
problematic data).
