OvmfPkg/VirtioDevice.h: Introduced VIRTIO_DEVICE_PROTOCOL protocol

This protocol introduces an abstraction to access the VirtIo
Configuration and Device spaces.
The registers in these spaces are located at a different offset and have
a different width whether the transport layer is either PCI or MMIO. This
protocol would also allow to support VirtIo PCI devices with MSI-X
capability in a transparent way (Device space is at a different offset
when a PCIe device has MSI-X capability).

OvmfPkg/VirtioMmioDeviceLib: Implement VIRTIO_DEVICE_PROTOCOL for VirtIo Devices over MMIO

Why is the virtio-mmio implementation of the protocol a library,
instead of a driver binary?
The UEFI driver model would encourage to create a virtio-mmio driver
instead of a library. But the reasons why I created a library are:

- A virtio-mmio driver would imply an additional protocol that would
probably have a single attribute field:

typedef struct {
  PHYSICAL_ADDRESS       BaseAddress;
} VIRTIO_MMIO_DEVICE_PROTOCOL;

- There is no (easy) way to scan the available VirtIo devices on a
platform. So, the UEFI firmware for this platform would need a driver
to produce instances for every virtio devices it wants to expose in
UEFI. A single call to a helper library (ie: VirtioMmioDeviceLib)
make the porting easier.

These casts are incorrect -- they throw away address bits >=32 before
shifting, which can break the drivers in guests with more than 4GB RAM.

The bug is clearly an artifact of the edk2 coding style, which requires
cast expressions to be written as

  (type) expression

rather than the usual

  (type)expression

The latter correctly reflects that casts have one of the strongest
bindings in C. The former actively obscures that fact. Cf.

  (type) expr1 >> expr2

vs.

  (type)expr1 >> expr2

Make sure we shift before we truncate.
