chore(mixins-preview): adding toDestination() to vended logs

[ShadowCat567]

Reason for this change

This is partially to support cross account vended logs, partially because being able to provide a deliveryDestination arn to set up a delivery connection is useful.

Description of changes

toDestination() allows VendedLogs to accept any CfnDeliveryDestination and will create a log delivery with it to the source resource that is provided.
