Make in RAM NetworkCommissioning::Featuremap report kThreadDevice (#14751)

* Switch default 'Network Commissioning'::'FeatureMap' attribute to 2

This makes the default in-ram setting claim 'I am a thread device'.
This is because most wifi devices already support a spec-compliant
network cluster:
  - linux reports as wifi
  - esp32 reports as wifi
  - darwin has an intentional 'report as 0' for unit tests which needs
    to be altered and ZAP defaults will not apply anyway.

Found files to be changed and validated via:

fd 'zap$' | xargs rg 'Network Commissioning' | cut -f1 -d: | uniq | xargs -n1 jq '.endpointTypes[].clusters[] | select(.name == "Network Commissioning") | {name: .name, attr: .attributes[] | {name:.name, default:.defaultValue, file: input_filename}} | select(.attr.name == "FeatureMap" and .attr.default != "2")'

* Ran zap regen

* Disable features on network configuration cluster on EP1. Not sure why we have 2 of them, likely they do not work

* Ran zap regen
