feat(tvix/eval): Allow passing in an env to evaluation r/8345
Allow passing in a top-level env, a map from name to value, to evaluation. The intent is to support bound identifiers in the REPL just like upstream nix does. Getting this working involves mucking around a bit with internals - most notably, locals now only optionally have a Span (since locals don't have an easy span we can use) - and getting that working requires propagating some minor hacks to places where we currently *need* a span (and which would require too much changing now to make spans optional; my guess is that that would essentially end up making spans optional throughout the codebase). Also, some extra care has to be taken to close out the scope in the case that we do pass in an env, to avoid breaking our assumptions about the size of the stack when we return from the toplevel Change-Id: Ie475b2d3dfc72ccbf298d2a3ea28c63ac877d653 Reviewed-on: https://cl.tvl.fyi/c/depot/+/11953 Tested-by: BuildkiteCI Autosubmit: aspen <root@gws.fyi> Reviewed-by: flokli <flokli@flokli.de>
