In HardwareSerial::write, bypass the queue when it's empty
This helps improve the effective datarate on high (>500kbit/s) bitrates, by skipping the interrupt and associated overhead. At 1 Mbit/s the implementation previously got up to about 600-700 kbit/s, but now it actually gets up to the 1Mbit/s (values are rough estimates, though).
