[Tizen][Runtime] Use tizen application id on tizen for wgt

To consistent with old wrt on tizen, we need to insert
[tizen_application_id] to tizen pkgmgr db when we install an
wgt packaged app, and we also need to launch an app by
[tizen_application_id].

For xpk, we still insert [xwalk.crosswalk_32bytes_app_id] to
pkgmgr db, and launch by it too.
