RFR: 8374324: Update copyright year to 2025 for jdk.compiler in files where it was missed

[Sergey Bylokhov]

The copyright year in "jdk.compiler" files updated in 2025 has been bumped to 2025.

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`
