Nate Cook 003b335351 [Observation] Switch Observable to be a non-marker protocol (#66993) ...

With support for redundant conformance declarations via macros,
the `Observable` protocol can be a non-marker protocol, which
provides more flexibility for evolution in the future.

This change also switches to the new ExtensionMacro protocol,
the requirement for which includes information about whether the
conformance to the Observable protocol has already been added, either
in the declaration or in a superclass to the macro-attributed type.
This allows the @Observable macro to be applied to subclasses of
observable types without redundant-conformance errors.
