branch-4.2: [fix](filecache) Preserve peer cache statistics in incremental
profile reports (#68987)
### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
On branch-4.2, `diff_file_cache_statistics()` omits ten peer cache
fields, causing incremental profile reports to lose cross-CG and same-CG
read counts, bytes and timers, peer race results, and lazy fetch
statistics.
The SNII backport (#68584) added assertions covering these fields
without including the corresponding delta calculations already present
on master. This causes three FileCacheProfileReporterTest cases to fail.
Add the missing field calculations to preserve these statistics in
incremental reports.
### Release note
None
