RFR: 8343775: Add since checker tests to the security area modules

[Nizar Benalla]

Can I please get a review for this PR that add tests to verify the value of `@since` tags to the Serviceability area modules. The test is described in this [email](https://mail.openjdk.org/pipermail/jdk-dev/2024-October/009474.html).

The benefit from this is helping API authors and reviewer validate the accuracy of `@since` in their source code (and subsequently, in the generated documentation). And lessen the burden on Reviewers.

The test has been added for `java.base` and a few other modules and has helped catch some bugs before they make it to the JDK.

Note: The test for `jdk.crypto.mscapi` is missing as I noticed a failure when running it on that module, I will add it in a future PR after patching the cause of the failure (Whether it's a missing `@since` or something else)

TIA
