[Infra] Replace MetricsUIAggregation in favor of `estypes.Aggregati…

…onsAggregate` (elastic#190495)

Closes [elastic#190311](elastic#190311)

## Summary

This PR replaces `MetricsUIAggregation` in favor of
`estypes.AggregationsAggregate`. Now the `MetricsUIAggregation` uses
estypes.AggregationsAggregate and the `MetricsUIAggregationRT `is
removed which also allows us to remove the `ESAggregationRT`. Instead of
maintaining the runtime types we now rely on the types provided by
elasticsearch.

A follow-up issue will be linked here to address the other aggregation
types related changes:
[elastic#190497](elastic#190497)

## Testing
- Check the types 
- Host page should load with no errors
- To test if the API works use the request provided in the
[x-pack/plugins/observability_solution/infra/server/routes/infra/README.md](https://github.com/elastic/kibana/compare/main...jennypavlova:kibana:190311-infra-replace-metricsuiaggregation-in-favor-of-estypesaggregationsaggregate?expand=1#diff-e853fdd3f4073eff8ff8a4df6a657f8cb5fefaa231be0116fe3692ae929f26a8)
- if the body is not valid 400 is returned
