8d9d84f33c refactor(library/blast): we don't require maximally shared terms anymore in blast 
This commit also removes the blast::mk_* expr and level functions.
They were just noops.

I kept only mk_uref, mk_href and mk_mref

Remark: they are temporary objects, and should never be included in the
blast state object.
