layout: Add a wrapper for adding the view to the hidden layer

And with it, use it *as well* when detecting a surface shouldn't be
presented if activate-by-default is disabled. The reason for doing that
is to allow application the resize and receive frame events right after
the client shell has been started.

Doing it a later point it time, right when a potential activation could
come from a client, wouldn't really be useful as the client won't react
to configure events. This particular fix is for cases where the
activate by default is disabled and the application itself was added
*before* the client shell sent the ready request.
