### Problem Description

ILM [SwapAliasesAndDeleteSourceIndexStep](https://github.com/elastic/elasticsearch/blob/ffcf0eac010df3b5ba7989c5dd87bf362dd0d311/x-pack/plugin/core/src/main/java/org/elasticsearch/xpack/core/ilm/SwapAliasesAndDeleteSourceIndexStep.java) doesn't play nicely with with hidden aliases. 

When we copy the aliases from the source index in the move step, we do not copy the is_hidden value.

This can lead to permanently bad ILM state with an error like:

```
policy [kibana-event-log-policy] for index [.kibana-event-log-7.11.1-000044] failed on step [{"phase":"frozen","action":"searchable_snapshot","name":"swap-aliases"}]. Moving to ERROR step java.lang.IllegalStateException: alias [.kibana-event-log-7.11.1] has is_hidden set to true on indices [...]; alias must have the same is_hidden setting on all indices at org.elasticsearch.cluster.metadata.Metadata$Builder.validateAlias(Metadata.java:2089) 
```

### Steps to Reproduce

Combination of ILM and hidden aliases.
