Support .callHookOnce

[pi0]

Describe the feature

Usually, there are some hooks that are to be called only once.

In the current API, it is delegated to hook consumers to use hookOnce on them; if they don't and use hook insteam, small callbacks might remain in memory.

A new .callHookOnce API can make sure it from provider-side and automatically discard all listeners after.

Second idea: We could also warn if a hook register attempt after callOnce that it won't be called and likely a late register issue
