Should the runtime host functions validate action inputs before creating the actions?

[nagisa]

Today we validate the contents of receipts and actions before executing them by eventually calling functions like runtime::verifier::validate_receipt, runtime::verifier::validate_action functions.

However, we also apply a similar check when creating some of the actions with the VMLogic host call. But not for others making this behaviour largely inconsistent and quite difficult to understand.

We should either remove all action validity checks from VMLogic or apply the validation consistently by e.g. making it part of the append_action helper.
