Robert O'Callahan 72a21fe01d Introduce `RmStats` struct to encapsulate removal statistics 
Turns out this is not strictly necessary for this PR but it's
still a good thing to do and makes it clearer that the stats
are not modified in a possibly racy way.

Robert O'Callahan c2bb7d6a82 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.

abhinavputhran 94c789e9c8 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
