> Miscellaneous refactorings/cleanups in `vm.runtime.defmeth` tests.

>   - replace `test/hotspot/jtreg/vmTestbase/vm/runtime/defmeth/scenarios` with enumeration of different test configurations in tests themselves; 
>   - pass `TestBuilder` as a parameter and initiate test execution from executor; 
>   - switch max class file version tested from 52 to 61 (`V17`); 
>   - minor changes (cleanups, new test cases)
> 
> Testing:
> - [x] vmTestbase/vm/runtime/defmeth/
> - [x] hs-tier5-rt - hs-tier8-rt
