Convert hooks to OO

Nice work! Verified that the `initial preprocess` approach is the standard practice

11.2-only feature so no backport needed.

Pretty sure the template preprocess needs only one `:` for the method, that's how @berdir has been doing it in conversions for core.

I had asked about it and since it's not a service a single is the way to do it.

Further, it doesn't hurt, but the empty post update hooks shouldn't be necessary either.

That's actually backwards, the two syntaxes are service:method and class::method. However, the code in CallableResolver has identical code paths after exploding on either amount of :, it processes them the same by passing onto ClassResolver::getInstanceFromDefinition()

Either way, it will work.

Thanks!
