Hui Xiao f69a5fe8ee Cap compaction_readahead_size by max_sectors_kb (#12937) ...

Summary:
**Context/Summary:**
https://github.com/facebook/rocksdb/issues/12038 reported a regression where compaction read ahead does not work when `compaction_readahead_size ` is greater than `max_sectors_kb` defined in linux (i.e, largest I/O size that the OS issues to a block device, see https://www.kernel.org/doc/Documentation/block/queue-sysfs.txt for more).

This PR fixes it by capping the `compaction_readahead_size` by `max_sectors_kb` if any. A refactoring of reading queue sys file is also included to reuse existing code.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12937

Test Plan: https://github.com/facebook/rocksdb/issues/12038#issuecomment-2327618031 verified the regression was fixed
