It would be great for Amplify CLI functions to support shared secrets

### Is this feature request related to a new or existing Amplify category?

function

### Is this related to another service?

_No response_

### Describe the feature you'd like to request

Currently amplify functions allows you to create secrets and environment variables which is very useful. However there are certain values that need to be reused between functions (ex: External Client Ids, External Secrets, etc.). Currently these need to be configured for each function.

### Describe the solution you'd like

I would love to have the ability to import an existing secret from an existing function to a new function I am creating.

### Describe alternatives you've considered

Currently the only option is to create copies of the same secret for every function, im looking into a custom cdk alternative as well at the moment.
