Minimize diff in google style inputs

Follow up after fix for initial implementation https://github.com/checkstyle/checkstyle/issues/17258

Suppression list were added at
https://github.com/checkstyle/checkstyle/blob/b24679c59d363d263156859fde87e488a5cb8b39/.ci/google-java-format.sh#L12-L15

We need to investigate if that is possible to avoid or minimize suppressions.
Original idea was to keep majority under 50 bytes diff, we should investigate ability to use it.

Split of files into few might be also a strategy.

Start with .ci/google-java-format.sh lines 12-15 and the follow-up context in issue 17258. Investigate whether the current suppression list can be reduced while keeping most changes under a 50-byte diff, and consider splitting files as mentioned. Done means documenting or implementing a reduced-suppression approach with an acceptable formatting diff.
