feat: replace DependsOn to connector by its generated logical IDs

[hoffa]

Issue #, if available

#2534

Description of changes

A connector logical ID in DependsOn will be automatically replaced by the logical IDs of its generated resources. This makes situations where DependsOn is necessary a little easier (e.g. event source mapping with DLQ), and it's consistent with how currently the abstract resources are referenceable.

For example, the following:

DependsOn:
  - SomeConnector

Will be replaced by:

DependsOn:
  - SomeConnectorWriteLambdaPermission

Nice!

LGTM. I originally thought this is better done via a plugin. But this seems more precise as each connector handles its own logical ID.
