We use `:` for cross-cluster search (eg `cluster:index`), therefore, we should not allow the ambiguity when allowing cluster or index names. Relates to elastic#23892

We currently fallback to local indices whenever a remote cluster is not found, as there may still be indices / aliases with the same name. Such behaviour is lenient but needs to be kept for backwards compatibility. Clarified that in the code so we don't forget. Relates to #26247

We support the cluster:index syntax in all the API that support cross-cluster calls. Those API will extract remote indices, properly resolve them, and resolve locally the local indices. API that don't support this syntax though end up attempting to resolve such indices locally, which in most cases leads to an index not found exception depending on how ignore_unavailable is configured for the API. The reason for treating these index names as local is that we used to support ':' in index names, but that is no longer supported since 7.x. That means that 7.x may still have indices with ':' in their names from 6.x, but 8.x won't. We can then switch 8.0 to throw a more specific error in place of the index not found, to signal that remote indices have been requested in the context of an API that does not support cross cluster calls. relates to elastic#26247

Silently failing makes it hard for users to know that they are even relying on a feature that is not supported, hence we'd like to start throwing error also in 7.x, similarly to what we did in elastic#74556. This commit introduces a check for remote indices that are locally resolved, which is an indication of cross cluster syntax used in API that don't support cross cluster calls. We then check if that index exists in the local cluster, and if so we proceed to resolve it as usual. If not, we throw a specific error that makes it clear to users that they are relying on cross cluster calls calling API that does not support them. relates to elastic#26247

This is for master (7.0+) with the intent to change it to deprecation warning/logging when backporting to the 6.0 and 6.x branches.
