fix(ecr): allow creating repository uri to use tokens like cfn params (#32053)

### Issue # (if applicable)

Closes #31860.

### Reason for this change
Currently customers can pass one property `tagOrDigest` and if the customers pass a CFN parameter, CDK could not know if it is a tag or digest, and so the generated URI is not correct.

Now the same parameter can supports Tokens, and it will generate a CFN condition to check if the value of this token is digest or tag, and then update the uri based on the condition output.


### Description of changes

Check if the input is a Token, and so instead of determining if its value is a tag or digest in synth time, we create a CFN condition to do this check in CFN, and then determine how to build the repo uri.

### Description of how you validated changes

Added unit test cases, and integration test cases with assertions.
