style(elasticloadbalancingv2): remove trailing whitespace and extra blank lines

- Remove trailing whitespace from application-listener.ts SSL policy calculation
- Remove trailing whitespace from network-listener.ts SSL policy calculation
- Remove trailing whitespace from enums.ts documentation comments
- Remove extra blank lines at end of ApplicationListener class
- Remove extra blank lines at end of NetworkListener class
- Remove extra blank lines at beginning of enums.ts file
- Remove extra blank lines between SslPolicy enum values
- Clean up formatting to improve code consistency and readability
