Introduced a configurable parameter to set the time offset (in ms) for scheduling Wi-Fi keep-alive frames earlier than the BSS max idle timeout advertised by the AP. This allows better compatibility with devices that may experience delays due to scheduling or processing. Signed-off-by: Ajay Parida <ajay.parida@nordicsemi.no>
Add a snippet for Wi-Fi keep alive schedule early offset setting. This will set the keep alive early schedule duration. Signed-off-by: Ajay Parida <ajay.parida@nordicsemi.no>

Why do we need a snippet with just single config?

| The supplicant schedules the keep-alive timer 100 ms prior to the BSS | ||

| help | |
| This setting tells your device how many milliseconds (ms) before the | |
| Access Point's (AP) maximum idle timeout it should attempt to send a | |
| Wi-Fi keep-alive packet. | |
| The main reason for this **grace period** is to build in extra time | |
| for your device's internal processes. If there are delays in getting | |
| the keep-alive frame ready and out the door, it could end up being | |
| sent *after* the AP's timeout, causing your connection to drop. | |
| Increasing this value helps ensure the packet is sent well in |
| There will be new PR for this. |
