    analyzer: factor out new class feasibility_state

    As preparatory work for a fix to PR analyzer/96374, this patch
    moves the core state-update logic from the loop in
    exploded_path::feasible_p into a new class feasibility_state.

    No functional change intended.

    gcc/analyzer/ChangeLog:
            PR analyzer/96374
            * engine.cc (exploded_path::feasible_p): Move "snodes_visited" =
and
            "model" locals into a new class feasibility_state.  Move heart
            of per-edge processing into
            feasibility_state::maybe_update_for_edge.
            (feasibility_state::feasibility_state): New.
            (feasibility_state::maybe_update_for_edge): New, based on loop
            body in exploded_path::feasible_p.
            * exploded-graph.h (class feasibility_state): New.=
