sl-radio-group should have a focus method

[schilchSICKAG]

As <sl-radio-group> already holds all the logic for form implementation, it should also be able to be focused programatically (e.g. document.querySelector('syn-radio-group').focus()). This feature currently only exists on <sl-radio-button>.

I would propose to add a focus method to <sl-radio-group> with the following features:

1. If the radio-group is disabled, do nothing
2. If there are only disabled radio-buttons, do nothing
3. If a value is set, select the radio-button that has the same value
4. If no value is set, select the first radio-button that is not disabled.

Any thoughts on this? Would be happy to provide a PR for this if the requirements are clear and you are interested.

Makes sense. What do you think? @lindsaym-fa @KonnorRogers

+1 from me. Thats the behavior I would expect.

Hey @claviska and @KonnorRogers, in this case I will give it a shot and provide a PR in the next couple of days. Just for the workflow: Should I open a new issue before doing so or just reference this discussion?
