pipeline: should allow crossRegionReplicationBuckets passthrough to underlying CodePipeline construct

[ahammond]

Describe the feature

When deploying large numbers of CdkPipelines, we consume a lot of S3 buckets. There is already a way to reuse the artifact buckets across multiple CdkPipelines. We would like to also reuse the cross region replication buckets. To do this, we need to pass through the crossRegionReplicationBuckets property from the Pipeline object to the internal CodePipeline object.

Use Case

There's a hard limit of 1000 S3 buckets per account. Our CdkPipelines deployer account supports pipelines from roughly 130 repos at this time and recently crossed the 900 bucket line. We need to be able to keep scaling out.

Proposed Solution

Pass the crossRegionReplicationBuckets through, same has how reuseCrossRegionSupportStacks is passed through:
