drivers: wifi: siwx91x: Add param change handling for STA and AP modes

Implemented logic to detect changes in key Wi-Fi parameters (SSID, PSK,
security, channel) and disable the interface accordingly. For STA mode,
the driver disconnects before reconnecting with updated parameters. For
AP mode, it disables and re-enables the AP if changes are detected.
