[lib] Deprecate useRoleDeletableAndEditableStatus and determine is[Editable/Deletable] directly in RoleActionsMenu

Summary:
Context: https://linear.app/comm/issue/ENG-6949/update-roledeletableandeditablestatus-to-use-specialrole-field

We can use specialRole field and roleIsDefaultRole and roleIsAdminRole utilities directly instead of doing this in a separate hook.

Depends on D11206

Test Plan:
Make sure that RoleActionsMenu appears and behaves as expected.

Will put screenshots in here shortly:
