Implement exit code on internal errors

[pszypowicz]

Describe the feature

When Checkov fails with an internal error, there is no distinction on exit codes.

Examples

Like for example I got the internal error, but due to --soft-fail I am not able to easily detect it and react to it.

Additional context

This is neccessary to make a proper pipeline logic, halt or rerun script on internal error, ignore if the checkov is running with a "soft-fail" flag.

Probably a duplicate of #3619 but it got closed and have no responses there.
