openthread: platform: Add temporary API migration code

The transmit functions will return an error code, instead of a boolean
value. To prepare for this, the API calls are temporarily implemented in
two variants, for old and new API declarations.

The presence of new API will be detected by the use of
NRF_802154_TX_FUNCTIONS_RETURN_ERROR_CODE macro, which will be
unconditionally defined by a newer nrf-802154 driver.
