RFR: 8352869: Verify.checkEQ: extension for NaN, VectorAPI and arbitrary Objects [v15]

[Emanuel Peter]

> We should extend the functionality of Verify.checkEQ:
> - Allow different NaN encodings to be seen as equal (by default).
> - Compare VectorAPI vectors.
> - Compare Exceptions, and their messages.
> - Compare arbitrary Objects via Reflection.
> 
> Note: this is a prerequisite for the Template Library [JDK-8352861](https://bugs.openjdk.org/browse/JDK-8352861) / https://github.com/openjdk/jdk/pull/23418.
