Suspend the app if app has gone behind

When an app's visibility is changed as background even the app
had not been get foreground event, this app should be suspended
to avoid running in background mode.
If the app has backgroundSupport mode, when suspeding, it will be
skipped.

This feature only can work with TV profile due to "wrt.getAppState"

This patch is depend on https://review.tizen.org/gerrit/204707
