What problem does this PR solve?
Implement a microbenchmark to quickly and efficiently identify issues with the Doris file cache, including performance problems. Direct end-to-end system tests that stress Doris to evaluate the efficiency of the file cache component are relatively ineffective, as they do not quickly yield the desired eviction rates and pressures, and may also be affected by factors such as compaction. Therefore, we need to implement direct testing of the file cache functionality and performance through the IO layer (S3FileWriter + CachedRemoteReader) during upload and download operations.
