> This is an alternative (and opposite) approach to https://github.com/openjdk/jdk/pull/24895. We basically convert most `[cds]` logs to `[aot]` logs. However, for the few logs that might be needed by existing user scripts, we use macros like `aot_log_info`, `aot_log_debug` so that they can be selected/printed using the `[cds]` tag. 
> 
> We have a few hundred logs that start with `[cds]`. To aid reviewing, this PR will convert only part of them. The rest of the logs are converted in https://github.com/openjdk/jdk/pull/25238. Both PRs will be integrated at the same time after review.
> 
> Please see **aotLogging.hpp** for how the macros work.
