Simplify Refcounting
...
Instead of -max_size to -1 for regular refcounts, use 1 to max_size.
0 still means constant refcount.
The highest bit is used to signify atomic refcounting required.
This does not turn on any sort of atomic refcounting.

Improve roc atomic refcounting by using first bit to indicate threadlocal
...
By avoiding atomic refcounting for any threadlocal variable, this greatly improves performance.
Leads to the performance of threadlocal refcounting being only ~4% behind non-atomic refcounting.
The old atomic refcounting could be as far as ~50% behind (though normally 10-20%).
This does not enable anything atomic related.
If we enable all forms of data loading (List.get, Box.unbox, loading recursive tag) to propagate the atomic flag,
this should be a reasonable implementation for roc by default.
With propagation, a platform would just set a list to atomic. On load, individual elements would also get set to atomic.
We also should probably revert back to threadlocal if an atomic refcount drops to 1.

change zig bitcode refcounting to require whether or not an element is refcounted
...
This also requires zig bitcode to have access to the dec functions for elements.
This is needed so that zig will be able to free elements in lists.

This changes Dict and Set to have a compilation depedent seed.
The seed is not exposed to userland in anyway.
