[nrf fromtree] Fix max timeout for open commissioning window (#35507)

Commissioning window can be opened using timeout exceeding
the maximum value of 900 s defined by the spec. This can happen
if selected transport is IP, but the device uses BLE extended
announcement feature.

Added checking if device is commissioned to be able to determine
what max timeout should be used for the particular scenario.

Renamed CHIP_DEVICE_CONFIG_BLE_EXT_ADVERTISING to the
CHIP_DEVICE_CONFIG_EXT_ADVERTISING, as config name sounds
misleading and it seems it relates only to BLE.

Fixes: #35505
