va: postproc, filter: add disable-passthrough property

vapostproc tries to be in passthrough mode as much as possible. But
they might be situations where the user might force to process the
frames. For example, when upstream sets the crop meta and the user
wants VA do that cropping, rather than downstream.

For those situations this property will disable the passthrough mode,
if it's enabled.
