Move Python tests from Common/Core to Wrapping/Python
Most of the tests in Common/Core/Testing/Python are testing the functionality of the wrappers, rather than testing classes in the CommonCore module. These tests often use classes that are outside of CommonCore. A better location would be Wrapping/Python/Testing. The dependencies of the test should be considered when deciding where to move them.
The following Python tests should remain in Common/Core: TestArrays, TestSOADataArrays, and TestVariant.
