The original change cleaned up code of static CDS. I am backporting it as a dependency of [JDK-8315130](https://bugs.openjdk.org/browse/JDK-8315130) which I will be backporting next: without this change the backport JDK-8315130 would need to include some parts of this change and would also leave some code unused.
Resolved conflicts:
- `src/hotspot/share/cds/unregisteredClasses.cpp`: bug fix [JDK-8343416](https://bugs.openjdk.org/browse/JDK-8343416) is missing in this version but the backported change itself incorporates the bug fix (to verify I checked that the backport makes [the test added in JDK-8343416](https://github.com/openjdk/jdk/commit/dde6230751672bde5a1bcb52686641f3a8b40cfb#diff-1db6a793c81a763792b2b6b2e80ce8a7d4d67288ea4adf9ee457c42d314698c4) pass, but I did not include that test in this PR)
- `src/hotspot/share/cds/classListParser.*pp`: constant pool resolution was added there in JDK 23/24 as part of Project Layden ([JDK-8293980](https://bugs.openjdk.org/browse/JDK-8293980), [JDK-8332176](https://bugs.openjdk.org/browse/JDK-8332176)) — this required only insignificant changes to the backport
- The rest of the conflicts were trivial (caused by renaming, neighboring code removal, copyright year updates)
The PR depends on #1833 though it can be rewritten not to if needed.
Testing besides the CI (performed on macos/arm64): `runtime/cds`, [test added in JDK-8343416](https://github.com/openjdk/jdk/commit/dde6230751672bde5a1bcb52686641f3a8b40cfb#diff-1db6a793c81a763792b2b6b2e80ce8a7d4d67288ea4adf9ee457c42d314698c4) (not included in the backport since that is a separate change).
