Refactor JavaScript list and array test cases

The JavaScript list and array test cases code has been restructured and moved into JavaScriptListsAndArrays directory. As a consequence, the previous Tests.cs file has been deleted. Additional test cases have been added to cover more scenarios, such as handling magic numbers in the code.
