[zephyr] Added Bluetooth LE Extended Advertisement option (#33005)
This commit implements platform solution for a Bluetooth LE
extended advertising.
Additionally, for the CommissioningWindowManager types were
changed from Seconds16 to Seconds32, because the current
implementation overflows for 48h duration.
