Add Azure deployment support for DTS projects

[MicroFish91]

High level flow - if DTS project detected, check for necessary DTS app settings on the function app. If missing, prompt user to select existing or create new DTS. Then:

• Prompt the user for a connected user assigned identity
• Add Durable Task Contributor role if missing
• Prepare that connection

Then resume deploy.

Of special note, I created a new FunctionAppUserAssignedIdentitiesListStep that can be used going forward to select existing function app identities to assign new roles to. It is currently missing the ability to create and assign new identities, which is a todo, but it works fine for selecting identities that are already associated with the function app. This PR is already pretty chonky as is so we can explore that implementation later.

Todo:

• Better activity log integration coming in follow-up PR (Add DTS deploy activity log integration #4574)
• I need to improve the logic so that it doesn't hard code the default connection keys
• Create and assign new UAID in the new list step?
