value: remove gst_value_register_{subtract,union,intersect}_func() API

Browse source 
There isn't really any need to provide public API for that. It's not
used anywhere in practice, and we aim to provide an API that works
for GstCaps, not some kind of generic set manipulation API based on
GValue. Making this private also makes it easier to optimise this
later. We can always put it back if someone actually needs it.
