convert: add classification for conv_attrs struct

Browse Source 
Create `enum conv_attrs_classification` to express the different ways
that attributes are handled for a blob during checkout.

This will be used in a later commit when deciding whether to add a file
to the parallel or delayed queue during checkout. For now, we can also
use it in get_stream_filter_ca() to simplify the function (as the
classifying logic is the same).
