bundle2: move function building obsmarker-part in the bundle2 module

We move it next to similar part building functions. We will need it for the
"writenewbundle" logic. This will allow us to easily include obsmarkers in
on-disk bundle, a necessary step before having `hg strip` also operate on
markers.

(Yes, the bundle2 module was already too large, but there any many
interdependencies between its components so it is non-trivial to split, this is
a quest for another adventure.)
