[Darwin] Enable OTA Provider server for controllers

[carol-apple]

Problem

Currently, to test OTA updates, the ota-provider-app and ota-requestor-app are used. In a more realistic scenario, a controller would likely be the OTA Provider. The OTA Provider server should be enabled for controllers

Proposed Solution

Enable OTA Provider server in src/controller/data_model/controller-clusters.zap

[bzbarsky-apple]

Controllers will need to do this as they choose, depending on their endpoint configuration.

For Darwin, this is now set up, with #15932 and #15887

Updating this issue to track the changes for Darwin only

[bzbarsky-apple]

In that case, I think this is more or less fixed. Remaining bits:

1. Make the Darwin server do mdns advertising. Created Enable operational advertising (and CASE server) in Darwin framework. #15951 for that.
2. Ensure that other nodes can create CASE connections to the Darwin server. Still sorting that out.
3. Implement an OTA provider delegate, etc.

The following PRs address the bare minimum needed to support OTA provider for Darwin controllers:

• Stop using the immediate default response bits in OTA provider. #15885
• Add OTA Provider server cluster to the Darwin framework. #15887
• Add non-generated IM dispatch to the Darwin framework. #15932
• Enable operational advertising (and CASE server) in Darwin framework. #15951
• Don't lose enableServerInteractions state when controller restarts. #16504
• Add an access control delegate implementation for the Darwin framework. #16546
