Move net unit tests to packages/Connectivity
Move the tests together with packages/Connectivity code, so both can be moved to packages/modules/Connectivity together. Also reorganize unit tests in a unit/ directory, as other tests (integration/, common/ etc.) have been added in tests/net since they were created. This makes the directory structure consistent. Test: atest FrameworksNetTests Bug: 187814163 Merged-In: I254ffd1c08ec058d594b4ea55cbae5505f8497cc Change-Id: I254ffd1c08ec058d594b4ea55cbae5505f8497cc
