RFR: 8374327: Update copyright year to 2025 for java.base in files where it was missed

[Sergey Bylokhov]

This patch updates the remaining files in java.base that were not covered by other recent PRs related to copyright updates.

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 `
