Add FrameworksMockingCoreTests to the automotive-tests package

Automotive team is running this test, we are migrating our tests into tradefed module runs
This means the tests need to be either in general-tests package, or device-tests package
We are not using those packages, so we need to add those tests into our own packages
either automotive-general-tests and automotive-tests
