RFR: 8352084: Add more test code in TestSetupAOT.java [v2]

[Ioi Lam]

> I modified TestSetupAOT.java to exercise more functionalities in the JDK so that we can have a more substantial AOT cache when running tests with `AOT_JDK=true`. E.g:
> 
> 
> make test JTREG=AOT_JDK=true \
>     TEST=open/test/jdk/java/util/TimeZone/ListTimeZones.java
> 
> 
> Before: the generated AOT cache was about 20 MB, with 2245 classes and 125 resolved indies
> After:  the generated AOT cache is about 34 MB, with 4703 classes and 912 resolved indies
> 
> I verified with Mach5 tiers 4, 5, 6, 10 with all tests tasks that have the label `.*aot.jdkcache.*`
