(#7289) Specify order for option decorations.

`before_action` decorations should always resolve in resolution order
from most general (inherited from furthest away) to most specific
(declared on the instance), and should always execute Face-level
option decorations before action-level option decorations.

`after_action` decorations should execute in the opposite order.
