This reverts commit 0dc598df.

Reason for revert: Fails the wasm-cache-test blink test.

Original change's description:
> [wasm] Refactor callback triggering
> 
> 1) Instead of passing three boolean values to |TriggerCallbacks|, pass
>    one EnumSet which contains all events to trigger.
> 2) Remember which events already happened, to avoid triggering them
>    again.
> 3) Compute triggered events once after the loop in |OnFinishedUnits|,
>    instead of checking for every finished unit.
> 4) When a new callback is registered, trigger all previous events
>    immediately. This solves issue v8:10217.
> 5) Replace |NotifyTopTierReady| by |AddCallback| which is identical now.
> 6) Do not call |OnFinishedJSToWasmWrapperUnits| if no wrappers were
>    compiled (this is a minor performance optimization; we save taking
>    and releasing a lock).
> 7) Drive-by: Make the |EnumSet| constructor really constexpr (by making
>    |Mask| constexpr).
