[2.0.0] Add BLE characteristic callbacks overloads (#4832)

Browse Source 
Add BLE characteristic callbacks overloads with esp_ble_gatts_cb_param_t* param.
Example:

class BleCharactCallback : public BLECharacteristicCallbacks
{
    void onRead(BLECharacteristic *pCharacteristic, esp_ble_gatts_cb_param_t *param)
    {
        auto addr = param->read.bda;
        ESP_LOGV(TAG, "Device " ESP_BD_ADDR_STR " request data", ESP_BD_ADDR_HEX(addr));
    }
    void onWrite(BLECharacteristic *pCharacteristic, esp_ble_gatts_cb_param_t *param)
    {
        auto addr = param->write.bda;
        ESP_LOGV(TAG, "Device " ESP_BD_ADDR_STR " transmit data", ESP_BD_ADDR_HEX(addr));
    }
};
