RFR: 8350704: Create tests to ensure the failure behavior of core reflection APIs [v2]

[Chen Liang]

> Core reflection's generic signature parsing system is used for many aspects, including annotations and enclosing methods, yet it is under-tested. It is better for us to set up tests to ensure that sensitive error behaviors of core reflection remain the same across implementation updates, such as #19281.
> 
> This patch also includes a JUnit converted version of https://github.com/openjdk/jdk/pull/22581#issuecomment-2521703511 test checking behavior around annotations with duplicate interfaces. Interesting that this causes failure in class, field, and methods (constructors), but not in parameters.
> 
> Testing: jdk-tier 1, jdk-tier 2
