RFR: 8374363: Update copyright year to 2025 for test/micro in files where it was missed

[Sergey Bylokhov]

The copyright year in "test/micro" files updated in 2025 has been bumped to 2025.

**Note:** I have skipped all files updated by the https://github.com/openjdk/jdk/commit/beb43e2633900bb9ab3c975376fe5860b6d054e0

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`
