Merge the two autoidx hashtables into one
...
When something calls `IdString::c_str()` on an autoidx ID, we need to cache the
full string in a thread-safe way. If we need to allocate an entry in some data
structure to do that, it's difficult to do in a thread-safe no-performance-hazard way.
So instead, store the cached string pointer in the same hashtable as the prefix
pointer.

Forbid creating IdStrings and incrementing autoidx during multithreaded phases, and add dynamic checks for that
...
We could make it safe to increment autoidx during multithreaded passes, but that's
actually undesirable because it would lead to nondeterminism. If/when we need new
IDs during parallel passes, we'll have to figure out how to allocate them in a
deterministic way, and that will depend on the details of what the pass does.
So don't try to tackle that now.

Remove YOSYS_NO_IDS_REFCNT
...
Refcounting is hardly used at all so this option is not that useful.
We might want to have a different option that disables GC if that becomes
a performance issue, but that should be a different option.
