Enable softap commissioning

[chshu]

Problem

The softap commissioning was implementated at the beginning, but not well maintained for a while, and it's not part of SDK 1.0 planning.

Recently we saw some requests from customers who want to try the softap commissioning:

1. Some resource constrained SoC can't run Wi-Fi and BLE stacks simultaneously;
2. Some customers want to integrate Matter and other protocols, and prefer to use softap commissioning instead of BLE.

To enable these Matter customers earlier, we want to maintain the softap commissioning feature in current SDK.

Per the spec, we divided the feature into several steps, and below is the verificaion results on ESP32 platform:

• [x] Device Discovery over Softap link
• [x] Establish PASE session over Softap link
• [x] Device attestation and Fabric provisioning over PASE session
• [ ] Network provisioning, commissionee join the operational network (https://github.com/project-chip/connectedhomeip/pull/17451)
• [ ] Establish CASE session over operational network (Currently It's established over Softap link)
• [ ] Invoke CommissioningComplete command and get response over CASE session

Some other features for productization：

• [ ] exclude BLE code if only enable Softap commissioning
• [ ] shutdown softap after commissioning is done (concurrent and non-concurrent)
• [ ] chip-tool auto switch network, from softap to operational network (is it necessary?)
• [ ] manufacturing provisioning for Softap commissioning

Proposed Solution

We will resolve the itemes listed above.
