Cherry-pick elastic#20540 to 7.9: Fix Winlogbeat export index-pattern…

… with migration.6_to_7.enabled (elastic#20628)

* Cherry-pick elastic#20540 to 7.x: Fix Winlogbeat export index-pattern with migration.6_to_7.enabled (elastic#20574)

* Test export commands in all Beats (elastic#20016)

This adds 4 new integration tests to all Beats that test export commands:

> beatname export ilm-policy
> beatname export template
> beatname export index-pattern
> beatname export config

* [Filebeat] Add export tests to x-pack/filebeat (elastic#20156)

* Add export tests to x-pack/filebeat

Add export sub-command tests to x-pack/filebeat and add an assertion for the
size the Kibana index-pattern due to the Kibana API limiting payloads to 1 MiB.

* Assert size of index pattern document is less than 1 MiB

* Fix Winlogbeat export index-pattern with migration.6_to_7.enabled (elastic#20540)

- Test export index-pattern with migration.6_to_7.enabled=true
- Always run these tests, not only when integration testing
- Remove conflicting Winlogbeat alias
