This will be the case when the referenced managed resource exists, but the field
from which we want to extract a value is empty. Consider for example a status
field that does not have a useful value until the resource has been created.
Blocking on the referenced resource field being non-zero is roughly equivalent
to blocking on the referenced resource being in condition Ready.

This commit introduces managed.APISimpleReferenceResolver, which satisfies the
managed.ReferenceResolver interface. This variant requires much less plumbing
and reflection because it expects that managed resources expose a single
ResolveReferences method that will optionally select and then resolve any
resource references. It also adds a new pkg/reference which contains a library
that managed resource authors _may_ choose to use to avoid reimplementing common
reference selection and resolution logic.
The existing managed.APIReferenceResolver implementation remains the default,
but is marked deprecated and will be removed once all managed resources use the
APISimpleReferenceResolver. Notably, the "reference resolution" condition is no
longer set by managed.Reconciler - managed resources will report reference
resolution issues via the Synced condition (i.e. as a ReconcileError).
