Issue:
bedrock: add method to Agent to manage when prepare agent gets run
### Describe the feature

When an Agent, Knowledge Base, or Action Group is created or updated, the agent needs to be prepared by calling the PrepareAgent API. There is already a custom resource to call PrepareAgent, but it is only available within the Agent resource. It is preferable to only call PrepareAgent once after all updates are made.

I would like to be able to add dependencies and optionally a changeId to the PrepareAgent custom resource from outside of the Agent resource.

### Use Case

While developing Agent Action Groups, I see that there needs to be a public way to add a dependency to Prepare Agent. Agent Action Groups depend on an Agent, but the Agent needs to be prepared after creating or updating the Agent Action Group.

### Proposed Solution

An internal method on Agent called `_addPrepareAgentDependency` can be called to add a resource and optionally a changeId so CloudFormation knows to update PrepareAgent when the resource is updated.

```ts
/**
 * Register a dependency for prepareAgent.
 *
 * @param resource - The resource that will be registered as a dependency.
 * @param changeId - The changeId of the resource that will be registered as a dependency.
 *
 * @internal This is an internal core function and should not be called directly.
 */
public _addPrepareAgentDependency(resource: cdk.IResource, changeId?: string) {
  this.prepareAgent.node.addDependency(resource);
  if (changeId) {
    this.changeIds.push(changeId);
  }
}
```

Usage:
```ts
props.agent._addPrepareAgentDependency(agentActionGroup, agentActionGroup.getAttString('changeId'));
```

Pull request description:
feat(bedrock): method to add deps to PrepareAgent
Fixes #229 

This change makes `changeIds` and `prepareAgent` private fields of agent and adds a public, but internal method named `_addPrepareAgentDependency` to resources created after the Agent, such as an upcoming Action Group, can be dependencies of the PrepareAgent custom resource.

Changes
* Moves the PrepareAgent custom resource to earlier in the file so the Agent and KB Associations can use  the method.
* Use the new method to make the agent and KB association custom resources dependencies of prepareAgent.
* Make prepareAgent a dependency of any aliases.
* Use cdk.Lazy to evaluate changeIds at the end of synth.
