vaapipostproc: make it enable/disable pass-through mode

Browse source 
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed

In addition, updating filter is performed during reconfiguration, if needed.
