samples: wifi: provisioning: Add new sample with internal transport
This is handy to test the core part of provisioning without worrying about BLE or SAP, this doesn't need any external dependencies, but still uses protbuf as the configuration mechanism, relies on Wi-Fi provisioning core library. Signed-off-by: Chaitanya Tata <[email protected]>
