Enable $out aggregation to push to time series collection

[HyunSangHan]

Closes: #4985

Context

Starting in MongoDB 7.0.3 and 7.1, $out can take a document to output to a time series collection:

{ $out:
  { db: "<output-db>", coll: "<output-collection>",
    timeseries: {
      timeField: "<field-name>",
      metaField: "<field-name>",
      granularity:  "seconds" || "minutes" || "hours" ,
    }
  }
}

Summary

Added time series collection support to $out aggregation operation.
Extend OutOperation to support MongoDB time series collections with configurable time field, metadata field, and granularity options.

• Add timeSeries() methods to OutOperation for fluent API
• Add static factory methods out() to Aggregation class
• Support both simple and extended $out syntax for time series
