Add --use-device-code as an option in config

### Describe the feature

In order to use `aws sso login` on non-local computers, you have to pass in `--use-device-code`. This should be an option as users who need to use the option will presumably always need to. Adding an option in the config as a convenience will be helpful.

### Use Case

Having to always add the flag when logging in is annoying.

### Proposed Solution

Add a login type in config:

```
[sso-session default]
...
login_type = device | pkce
```
