fix: simplify interface between grind core and cutsat (#8564 )

This PR simplifies the interface between the `grind` core and the cutsat
procedure. Before this PR, core would try to minimize the number of
numeric literals that have to be internalized in cutsat. This
optimization was buggy (see `grind_cutsat_zero.lean` test), and produced
counterintuitive counterexamples.
