RFR: 8374316: Update copyright year to 2025 for hotspot in files where it was missed [v4]

[Sergey Bylokhov]

> The copyright year in hotspot files updated in 2025 has been bumped to 2025. (to minimize... the patch...for now, all files modified by the commits in src/hotspot have been updated only.)
> 
> The next command can be run (on top of this PR) to verify that each file had prior commits in 2025:
> 
> `git diff HEAD~1 --name-only | while read f; do git log HEAD~1 --since="2025-01-01" --oneline -- "$f" | head -1 | grep -q . || echo "NOT IN 2025: $f"; done `
