Improving return types of action creators by adding generic args type

[salguerooo]

The reason for this is to have better autocomplete on the created actions.
It seems like a very niche use, but I ran into it and would like to have better autocompletes.

Also improves the LocationState type inside LocationDescriptorObject, before it was aways any.

Hi @salguerooo. Sorry for my delayed response. Is there any backward compatibility issue that we should be aware of?

[salguerooo]

Hey @supasate, Hmm there might be if someone is implementing the CallHistoryMethodAction and LocationActionPayload interfaces, I can't find a reason anyone would do that, but one way of making it backwards compatible would be to default those generics to any, something like export interface LocationActionPayload<A = any> {

Should I do the change?

Hey @supasate, I made the changes, what do you think?
