    Add `#pragma once` for PendingAction.h (#8846)
    
    PendingAction.h needs a `#pragma once` to protect it from double
    inclusion. This patch adds this. This has not caused problems yet
    because it is currently only used once in HttpSM.h, but as it gets more
    use this will be required.
    
    (cherry picked from commit 214b89261396f11c0866ce5f934ba24ca53ecde2)
