aws-rds: RDS Database Cluster support for GlobalDatabaseIdentifier

### Describe the feature

Add _GlobalClusterIdentifier_ parameter to rds DatabaseCluster construct, in order to be able to add database clusters to Global Aurora Databases, for example in different regions. The parameter is already supported through Cloudformation.

### Use Case

I want to add a database cluster in a different region to my Aurora Global Database cluster using CDK. This should be possible through the _GlobalClusterIdentifier_ parameter.

### Proposed Solution

_No response_

### Other Information

_No response_

### Acknowledgements

- [ ] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### CDK version used

2.40.0

### Environment details (OS name and version, etc.)

OSX

Start by locating the RDS DatabaseCluster construct and its CloudFormation resource mapping. Check how existing construct parameters are exposed and synthesized, then verify that the requested GlobalClusterIdentifier value is accepted and appears in the generated CloudFormation for an Aurora global database cluster.
