RFR: 8329351: Add runtime/Monitor/TestRecursiveLocking.java for recursive Java monitor stress testing

[Fredrik Bredberg]

@dcubed-ojdk is too busy, so I was asked to take over [https://github.com/openjdk/jdk/pull/18664](https://github.com/openjdk/jdk/pull/18664) and finish it.

That old PR contains all the details and also got some review comments, which I have tried to address in this new PR.

Tests run without failures on supported platforms.
