`Compiled` metadata is not used

[genieplus]

The Compiled field in App and Command struct is not used neither printed with the default help template.
Shall it be removed ?

[ddnomad]

I'd say it should be added to --version output

[asahasrabuddhe]

@urfave/cli your opinions here?

[coilysiren]

I need this issue to have a bit more context on the field in question, and some possible issues that could arise from removing it or adding it to the version output.
