(aws-timestream): Add support for CfnDBParameterGroup of Timestream InfluxDb

### Describe the feature

Currently, we don't have any feature to create a database parameter group using CDK following this guide
https://docs.aws.amazon.com/timestream/latest/developerguide/timestream-for-influx-db-connecting.html#timestream-for-influx-parameter-groups-overview-default-custom-parameter-groups
We have to do it manually and after that edit the `dbParameterGroupIdentifier` of `CfnInfluxDBInstance`

### Use Case

Create a database parameter group with CDK

### 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

2.126.0 (build fb74c41)

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

Linux

Start with the existing CfnInfluxDBInstance entry point and the AWS Timestream InfluxDB parameter-groups guide linked in the issue. Determine how CfnDBParameterGroup should be exposed alongside the instance and how its dbParameterGroupIdentifier is referenced. Done means CDK can define the parameter group and use it when creating the InfluxDB instance.
