IP cluster-based commissioning (#6798)

* Cluster-based commissioning - phase 1.

Adds calls to clusters to commission a device properly. This is
intended to be used to setup a device that is already on the
network, but not already on a CHIP network. Hence, network
credentials are not required, but we do need to send all the
remaining commissioning information.

Challenges:
IM cluster commands time out more often than the non-IM commands,
even when the device is clearly sending a reply.
Need to find the race and get rid of it.

Still to do:
- add operational credentials into state machine
- add more commissioning phases (time set etc.)
- add proper scan command for determining ethernet netif name
- swap over to CASE before sending commissioning complete command
- once we're totally in IM, combine some commands
- add post commissioning setup commands (trusted node ids etc.)

* Restyled by gn

* Address review comments.

* Add back some lines lost in a rebase.

* Address review comments

- remove heap allocation from callbacks
- overwrite node ID resolution functions rather than using a delegate

* Restyled by gn

* Restyled by shfmt
