[12] RFR of JDK-8210353: Move java/util/Arrays/TimSortStackSize2.java back to tier1

[Amy Lu]

test/jdk/java/util/Arrays/TimSortStackSize2.java

This test was demoted to tier2 due to JDK-8199265 (test fails with OOM). 
This issue has been fixed (in jdk-11+20) and test has been run (in 
tier2) without failure happening after that.

Let's move it back to tier1.

bug: https://bugs.openjdk.java.net/browse/JDK-8210353
webrev: http://cr.openjdk.java.net/~amlu/8210353/webrev.00/

Thanks,
Amy
