gst: Add utility to convert StreamFormats to GstCaps
This transforms the basic information found in StreamFormats to GstCaps.
This can be handy to reply to early caps query or inside a device
provider. Note that we ignored generated range as they are harmful to
caps negotiation. We also don't simplify the caps for readability
reasons, so some of the discrete value may be included in a range.
