RFR: 8376038: Refactor java/sql tests to use JUnit

[Justin Lu]

Please review this PR which converts the JDBC TestNG tests to use JUnit.

This is mainly done using the automated tool in https://github.com/openjdk/jdk/commit/0cec3097aec02e72ccb6ebbf0b2b046220578d1b, with some manual follow up commits. The testng folder is migrated to junit with the TEST.properties updated as well. Most changes are annotation updates and switching from testNG imports to JUnit. I decided to simplify cases of `BaseTest.trueFalse()` to use booleans in a `ValueSource` directly in https://github.com/openjdk/jdk/commit/757e7966666d39748db2912b32ccf8b1df18bd62.

Framework test stats before:
680 = 680 TestNG + 0 JUnit

Framework test stats after:
680 = 0 TestNG + 680 JUnit
