RFR: 8373935: Migrate java/lang/invoke tests away from TestNG [v2]

[Chen Liang]

> Refactor java/lang/invoke tests to use JUnit instead of TestNG.
> This is done by:
> 1. First a round of automatic conversion
> 2. Simplify exception handling tests
> 3. Replacing `assert` keyword and switching to better assertion APIs for equality etc.
> 4. Some other random cleanups, such as module status
> 
> Testing: java/lang/invoke on Linux-x64. I un-problemlisted the updated `java/lang/invoke/lambda/LambdaFileEncodingSerialization.java` too.
