Update connectivity TEST_MAPPING

 - Move Tethering TEST_MAPPING up one level to merge with the general
   Connectivity TEST_MAPPING. This allows running the tethering tests
   on any connectivity change.
 - Move TetheringIntegrationTests from postsubmit to presubmit
 - Add TetheringCoverageTests to mainline-postsubmit, so it can be
   added to mainline-presubmit later.
 - Import NetworkStack tests so that they are run on any connectivity
   change.

TetheringIntegrationTests were continuously green in postsubmit.
