[lib][native] Introduce useRoleNamesToSpecialRole to remove "Admins" string check in RolePanelEntry

Summary:
Context: https://linear.app/comm/issue/ENG-6950/update-rolepanelentrypanel-to-use-specialrole-field

We introduce this hook so we can get rid of "sketchy" string check in RolePanelEntry.

Depends on D11204

Test Plan:

• Log value of specialRole in RolePanelEntry to ensure it's being passed in properly
• Look at RolePanelEntry before/after and ensure that things continue to look as expected (will add screenshots shortly)
