Subject: [PATCH] autoconvert: Force raw memory when using videoconvertscale

videoconvertscale advertises `ANY` feature, but it supports it only
in passthrough. Our goal with autoconvert is to ensure that  conversion
is possible with the elements that are being plugged so we avoid
plugging `videoconvertscale` if the memory type is not system memory.
