Move list / dict tests to TestList and TestDict (pytorch#22000)

Summary:
There aren't any substantive changes aside from some test renames (e.g. `TestScript.test_dict_membership` -> `TestDict.test_membership`) and the addition of `TestDict.dict()`.

Adding the rest of the dict ops was making the tests a mess and `TestScript` is already > 10000 lines by itself, so breaking them up should make things cleaner
