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.

Hi Justin

Thank you for taking this on.

As part of this PR, we should also tackle javax/sql as they refer back to some of the code in this area.


We probably can look to convert the JavaTimeTest.java to junit and then we can up level from the junit, formally testing, folder.

A couple of other quick comments below

test/jdk/java/sql/junit/test/sql/CallableStatementTests.java line 135:

> 133:     @Test
> 134:     public void test08() throws SQLException {
> 135:         Assertions.assertThrows(NullPointerException.class, () -> cstmt.enquoteNCharLiteral(null));

Maybe use an import so we can shorten to just assertThrow?

test/jdk/java/sql/junit/util/BaseTest.java line 80:

> 78:      * DataProvider used to specify the standard JDBC Types
> 79:      */
> 80:     protected Object[][] jdbcTypes() {

Suggest converting all of these methods to use Stream<Arguments> and return Stream.of.
