Paul Hu 469c5d69e5 Move more network unit tests to common tests 
This adds the moved tests to CTS as well.
The moved unit tests are appropriate for CTS as they test data holder
classes that need to function properly for apps to work.

Test: atest FrameworksNetTests
Test: atest CtsNetTestCases: added tests pass
Bug: 129199900
