obj: move parsing utilities out of io_common, since they are fairly obj specific

As pointed out in https://developer.blender.org/rB213cd39b6db387bd88f12589fd50ff0e6563cf56#341113,
the utilities are quite OBJ specific due to treating backslash as a line
continuation character. It's unlikely that other formats need that.

No functionality changes, just pure code move (and renamed tests so that
their names reflect obj).
