docs: refresh V3 feature status (#2053)
Update the matrix to match current V3 support:
* mark partitioned DV writes as supported
* split Geometry/Geography status and note deferred geography/nested bounds
* clarify encryption metadata support vs file-level encryption
* add StatisticsFile / PartitionStatisticsFile support and NDV roadmap
