(hotswap): hotswap support for AWS::Bedrock::Agent

### Describe the feature

CDK CLI hotswap should support [`AWS::Bedrock::Agent` resource](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-bedrock-agent.html) to quickly deploy the configuration of Agents for Amazon Bedrock agents.

### Use Case

When we develop an agent of Agents for Amazon Bedrock, we need to deploy CFn template a lot. The definition of an agent contains an instruction, descriptions for available tools, system prompt overrides, etc. Every time we change these configurations, we have to wait 30~60s to deploy the CFn stack. If we can deploy it with hotswap (which usually finishes in a few seconds), it would improve the test cycle greatly.

### Proposed Solution

We can refer to previous pull requests like aws/aws-cdk#27197 as an implementation reference.
