[genio] several bug fixes for multiple devices and interop (project-chip#22951)

* Report exchanged MTU size to core for BLE transaction
* Add mdns refresh after IP address update
* Migrate MatterPostAttributeChangeCallback() to current prototype
* Discriminator as gatts device name
* Get wifi mac address by filogic wifi opmode mode
* Update submodule genio-matter-bsp, lwip
