The UEFI driver model invokes the supported() method on every driver
every time a connection attempt is made on any handle, and so doing an
unconditional DEBUG() print inside this method produced a lot of noise.
So let's drop this DEBUG() call from the VirtioSerial driver's
Supported() method.

Apparently TPL_CALLBACK is too low, code runs into an ASSERT
complaining the new TPL is lower than the old TPL.

Add a driver for the virtio serial device.
The virtio serial device also known as virtio console device because
initially it had only support for a single tty, intended to be used as
console. Support for multiple streams and named data ports has been
added later on.
The driver supports tty ports only, they are registered as SerialIo
UART in the system.
Named ports are detected and logged, but not exposed as devices. They
are usually used by guest agents to communicate with the host. It's not
clear whenever it makes sense for the firmware to run such agents and if
so which efi protocol could be to expose the ports. So leaving that for
another day.
