redshift: CfnCluster CreateCluster : Debug message

### Describe the bug

Redshift cluster would not deploy, and the error message was "Error Message: Not Found Resource of type '%s' with identifier '%s' was not found". This led to a trial-and-error debug session that took some time. This issue asks to update this error messaging.

### Expected Behavior

The condition should give a more descriptive error, such as:

ManageMasterPassword is false/not set and MasterUserPassword is not provided.

### Current Behavior

HelloCdkStack | 0/3 | 12:50:14 PM | UPDATE_FAILED | AWS::Redshift::Cluster | DemoCfnCluster Resource handler returned message: "Cluster democlusterid5 Not Found Resource of type '%s' with identifier '%s' was not found." (RequestToken: ec18d1c3-6003-09e1-f260-5f747d4619c1, HandlerErrorCode: NotFound)

### Reproduction Steps

CreateCluster
* Do not provide MasterUserPassword
* Do not provide ManageMasterPassword

### Possible Solution

The condition should give a more descriptive error, such as:

ManageMasterPassword is false/not set and MasterUserPassword is not provided.

The issue identifies the CfnCluster CreateCluster path and provides reproduction steps: omit MasterUserPassword and ManageMasterPassword. Start by locating that implementation and its existing error handling; done means this configuration produces a descriptive validation error instead of the generic NotFound message.
