Bedrock: Cross Region Inference Constructs

### Describe the feature

Abstractions for Bedrock cross region inference profiles and their identifiers ([see](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference-support.html)), similar to those for Bedrock foundation models ([see](https://github.com/aws/aws-cdk/blob/main/packages/aws-cdk-lib/aws-bedrock/lib/foundation-model.ts))

### Use Case

To grant a principal permission to invoke a cross region inference profile along with the associated foundational model in all supported regions. For example ([see](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference-support.html)), the US Anthropic Claude 3 Haiku profile is supported in `us-east-1` and `us-west-2`. To invoke this profile in `us-east-1` a principal must have permission to invoke the profile in `us-east-1` and the Anthropic Claude 3 Haiku foundation model in `us-east-1` and `us-west-2`.

### Proposed Solution

_No response_

### Other Information

The abstractions may also be useful for #31570

Start by reading packages/aws-cdk-lib/aws-bedrock/lib/foundation-model.ts and the AWS cross-region inference support documentation linked in the issue. Define the required profile and identifier abstractions, including the associated foundation models and supported regions, so a principal can receive the permissions described in the use case; confirm compatibility with #31570.
