perf(core): don't allocate if BLE event data is empty

Browse Source 
BLE event data is not empty only on pairing:
```
core/embed/io/ble/stm32/ble.c
176:      ble_event_t event = {.type = BLE_CONNECTED};
182:      ble_event_t event = {.type = BLE_DISCONNECTED};
227:  ble_event_t event = {.type = BLE_PAIRING_REQUEST, .data_len = 6};
244:  ble_event_t event = {.type = BLE_PAIRING_CANCELLED, .data_len = 0};
```
