CBG-5367: add metadata store to dcp client for both CBS and rosmar

[gregns1]

CBG-5367

Adds ability to pass down metadata store into dcp client for both rosmar and CBS

Pre-review checklist

• Removed debug logging (fmt.Print, log.Print, ...)
• Logging sensitive data? Make sure it's tagged (e.g. base.UD(docID), base.MD(dbName))
• Updated relevant information in the API specifications (such as endpoint descriptions, schemas, ...) in docs/api

Dependencies (if applicable)

• CBG-5367: metadata store as feed argument sg-bucket#145
• CBG-5367: make changes to pass metadata store into rosmar dcp client couchbaselabs/rosmar#74
• Update Go module dependencies when merged

Integration Tests

• https://jenkins.sgwdev.com/job/SyncGatewayIntegration/645/
• https://jenkins.sgwdev.com/job/SyncGatewayIntegration/649/ (re-run package from failing test above)

Pull request overview

This PR wires a metadata store through DCP client setup so persistent DCP checkpoints can be stored outside the streamed collection, covering both Couchbase Server and Rosmar-backed feeds.

Changes:

• Adds MetadataStore to DCP client option structs and forwards it to GoCB and Rosmar DCP clients.
• Updates import, resync, attachment migration, and attachment compaction DCP option construction to pass database metadata stores.
• Bumps sg-bucket and rosmar module versions and updates related tests.
