RFR: 8377777: Improve logging when rejecting assets from the AOT archive [v4]

[María Arias de Reyna Domínguez]

> Restored the check `if (resolved)` when printing if a CP entry is rejected or archived. If it is not resolved, we shouldn't even bother with it.
> 
> Also, added log messages (mostly based on surrounding comments) on `ConstantPoolCache::can_archive_resolved_method` to add information about why a method gets rejected.
> 
> All the log messages have the same format to be able to parse them easily:
> 
> ` log.print("%s can't be archived because $REASON.",
>                 pool_holder->name()->as_C_string());`
