Support non-zero exit codes as success

[denelon]

Description of the new feature/enhancement

Some applications return non-zero codes that are not errors. There should be a way for the client to know the difference between these codes and actual errors.

Proposed technical implementation details (optional)

A key could be added to the manifest syntax to indicate which non-zero codes should be treated as success. The client could then treat these non-zero return codes as success.

This is the case with installers wrapped in a WinRAR self-extracting archive, for example (e.g. microsoft/winget-pkgs#535). RARSFX will return exit code 1000 if the installation succeeded, and any other code indicates an error.

This also impacts adobe digital editions, and there are plenty more documented in installers listed on chocolatey/scoop https://chocolatey.org/packages/adobedigitaleditions#files.
