[native] Populate the create role screen
Summary:
This diff adds the necessary content to the create roles screen, i.e. a role name input and a panel of selectable permissions for the given role. The onSave functionality will be added in a later
diff, as well as the removal of the eslint-disable-next-line no-unused-vars.
Depends on D8379
Test Plan:
Navigated to the screen and typed in different role names, selected several permissions, tried clearing all permissions at once, and tried deselected some permissions individually.
