feat(tvix/eval): Support builtins.substring r/4916
Nix's `builtins.substring`: - doesn't accept negative indexes for `beg` or `end`. Compare the error messages for: - `builtins.substring -3 5 "testing"` - `builtins.substring 3 -5 "testing"` - `builtins.substring -3 -5 "testing"` - returns an empty string when `beg >= end` - allows `end` to exceed the length of the input string Change-Id: I83af7a099d81b6d537ebe5029d946c7031cb7113 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6555 Reviewed-by: wpcarro <wpcarro@gmail.com> Autosubmit: wpcarro <wpcarro@gmail.com> Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI
