Add more missing AggregationBuilder getters (#25198)

* Add more missing AggregationBuilder getters

- getMetadata for all aggs
- various getters on TermsAggBuilder (without "get" prefix to maintain convention)
- Also makes InternalSum's ctor public, to follow suit of other metrics (min/max/avg/etc)
