<i18n dev> RFR: 8373830: Refactor test/jdk/java/time/test tests to use JUnit over TestNG [v2]

[Justin Lu]

> Please review this PR which migrates the java.time tests from TestNG to JUnit. The java.time tests use TestNG based on the directory level settings configured by TEST.properties, so they are best migrated altogether. This is a large PR, so I have tried to make the changes clear by commit.
> 
> First, the auto conversion tool is run in https://github.com/openjdk/jdk/commit/b1fd7dbdec85aac5a44cc875e57a36be8f1b6974.
> https://github.com/openjdk/jdk/commit/3805cfd8765c0c76b61893dcf1670951402f98c3 and https://github.com/openjdk/jdk/commit/b697ca5d9a8067bcecea2dfb32f92f7699085dee are required so that the tests can actually compile and run.
> https://github.com/openjdk/jdk/commit/d07c912c4c16d2b3307e489563f148f71cfdf4a4 addresses the timeout annotation which was not covered by the auto conversion tool.
> The rest of the commits are aesthetic related.

> Framework-based tests: 32,339 = 32,339 TestNG + 0 JUnit
