RFR: 7903319: The methods 'getAllMethods' and 'getMethods' in class 'BenchmarkGeneratorUtils' have the same feature

[Guoxiong Li]

Hi all,

Currently, the methods `getAllMethods` and `getMethods` in class 'BenchmarkGeneratorUtils' have the same feature. This patch removes `getMethods` and keeps `getAllMethods`  because `getAllMethods` is consistent with `getAllFields`.

Thanks for taking the time to review.

Best Regards,
-- Guoxiong
