Make keep_cache_t process all modules up-front instead of on-demand
...
We will want to query `keep_cache` from parallel threads. If we compute
the results on-demand, that means we need synchronization for cache
access in those queries, which adds complexity and overhead. Instead, prefill
the cache with the status of all relevant modules. Note that this doesn't
actually do more work --- we always consult `keep_cache` for all cells of
all selected modules, so scanning all those cells and determining the kept
status of all dependency modules is always required.
Later in this PR we're going to parallelize `scan_module` itself, and that's also
much easier to do when no other parallel threads are running.

setundef: respect selection for cells, processes, and connections
...
Previously, setundef would rewrite sigspecs in all cells, processes,
and connections regardless of the active selection. Only modules and
memories were correctly filtered by selection.
Fix by using module->selected_cells() for cells, adding a
module->selected() check for processes, and checking wire selection
on the lhs of each connection before rewriting.
Fixes #5624

abc9: preserve topological-loop asserts with targeted SCC fallback
...
A real-world ABC9 flow hit residual combinational loops after SCC breaking, tripping the prep_xaiger loop assertion.
Keep the existing topological assertions in place (prep_xaiger and reintegrate still assert no_loops).
To handle residual non-box loops, add a targeted fallback in prep_xaiger: when loops remain after normal SCC breaking, insert additional $__ABC9_SCC_BREAKER cuts on non-box loop cells, rebuild toposort, and then re-check the existing assertion.
Also keep pre-ABC9 SCC tagging on all cell types (scc -all_cell_types) and add a regression test (tests/techmap/abc9-nonbox-loop-with-box.ys).
