feat: Add the ability to set the action and reusable workflow access level

[wwsean08]

Resolves #1418

---

Behavior

Before the change?

• There was no way to specify the action access setting to allow other repositories to use your private/internal repositories actions and reusable workflows in their own.

After the change?

• This allows you to set whether or not another repository in within your user, organization, or enterprise can use this repositories actions and reusable workflows.

Other information

• Tested via unit tests for both user and organization, see screenshots below
• I did find that allowed_actions needed to be set when using this, so there may need to be some additional logic to allow this setting alone. But if that is considered acceptable I will leave it.

After trying to dig in and figure out how to handle both of the scenarios of managing actions within the repo and managing access to the repo's actions and reusable workflows I have come to the conclusion there isn't a good way to do this within one resource. I'll open a new PR with a new resource which should make life much simpler.
