Remove string[] args from Main methods under JIT/Methodical (#63770)

In most cases the arguments were formal and not really used so
I just fixed the Main method signature. In a bunch of cases the
command-line arguments supported variant functionality of the
test case but I haven't found any test projects that would be
exercising this functionality. I don't think it makes sense to
keep untested code paths so I deleted the logic pertaining to
non-empty command-line arguments.

In the particular case of stringintern tests, each test apparently
had a TestSameObjRef and TestDiffObjRef variant, triggered by
command-line arguments. I tried to run TestDiffObjRef but it
ended up failing left and right - not suprising for untested
code logic - so I also deleted the TestDiffObjRef variants
as I suppose the invariants previously tested there no longer hold.

Thanks

Tomas
