Fix pairing via the SetupCodePairer

[sagar-apple]

Problem

SetupCodePairer doesn't need to use the BLE auto commissioning mechanism.

Instead its purpose is to establish PASE by parsing the onboarding payload and figuring out whether the commissionee is on BLE or IP.

Change overview

Only establish a PASE session inside the SetupCodePairer when the node was discovered over BLE and perform a full commissioning when it's on-network.

Also fixed iOS CHIPTool and exposed the Commission API to ObjC.

Testing

How was this tested? (at least one bullet point required)

• If manually tested, what platforms controller and device platforms were manually tested, and how?
  Verified that chip-tool qrcode/manualcode pairing is no longer broken.

[sagar-apple]

I need to make some changes to this PR to get it to pass CI.
I'm also working on fixing the iOS CHIPTool's commissioning flows as part of this. The PR will not pass CI until then.
