Hard code permission->group mapping into PermissionsController

The platform does not define the mapping anymore. We can now change the
mapping in an update of this app by modifying the hard coded table.

Test: atest CtsAppSecurityHostTestCases:android.appsecurity.cts.PermissionsHostTest
      atest --test-mapping packages/apps/PermissionController:presubmit
