RFR: 8376277: Migrate java/lang/reflect tests away from TestNG [v2]

[Chen Liang]

> Mostly routine conversions. Manual updates are mostly assertThrows migration, assertArrayEquals fixes, and removal of TestInstance to convert method sources to be static.
> 
> Notably, I avoided assertThrows migration in `ChainedReflection` and `IllegalArgumentsTest` because they seem to be very sensitive to low-level reflection and runtime stuff that I fear using test framework may accidentally harm.
