Add `GetActorValueIdFromName`

[fireundubh]

I use this function in LibFire.

Usage example:

if (const auto actor = a_ref->As<RE::Actor>(); actor) {
    const auto actorValueId = GetActorValueIdFromName(a_actorValue.c_str());  // <-- a_actorValue is of type RE::BSFixedString
    const auto actorValue = static_cast<RE::ActorValue>(actorValueId);
    return actor->GetPermanentActorValue(actorValue);
}

Thanks, been very busy this weekend, but I'll check this out after the weekend and update the PR.

This already exists as RE::ActorValueList::LookupActorValueByName

How are you supposed to use this? edit: Got it.

if (const auto actor = a_ref->As<RE::Actor>(); actor) {
    const auto actorValueList = RE::ActorValueList::GetSingleton();
    const auto actorValueId = actorValueList->LookupActorValueByName(a_actorValue.c_str());
    const auto actorValue = static_cast<RE::ActorValue>(actorValueId);
    return actor->GetPermanentActorValue(actorValue);
}

if (const auto actor = a_ref->As<RE::Actor>(); actor) {
    const auto actorValue = RE::ActorValueList::GetSingleton()->LookupActorValueByName(a_actorValue);
    return actor->GetPermanentActorValue(actorValue);
}
