jljusten b0f5144676 OVMF: Add Block MMIO protocol definition
This protocol is similar to the standard UEFI BlockIo protocol,
except it has no function calls and simply defines a base address
in memory where reads & writes for the block device should occur.

One planned usage is to fill a memory region with a small disk
image, and allow it to be used as a normal disk by the
standard drivers.

jljusten 9607962def OVMF: Add support for saving the NV variables to disk following each SetVariable call.
Note:
* This only works before ExitBootServices
* For OVMF, variables are only preserved on the disk if there
  is a hard disk connected which has a writeable FAT file system.

The Ovmf/Library/EmuVariableFvbLib library will look for the
gUefiOvmfPkgTokenSpaceGuid.PcdEmuVariableEvent PCD to be set to
a non-zero value.  If set, it is treated as an event handle, and
each write to the EmuVariableFvb will cause the event to be
signaled.

In this change, the OVMF platform BDS library sets up this event,
and sets the PCD so that after each write to the EMU Variable FVB,
the non-volatile variables will be saved out to the file system.

The end result is that NV variables that are written prior to the
ExitBootServices call should be preserved by storing them on the
disk.

jljusten 5094454579 Implement NvVarsFileLib to save and restore non-volatile variables using a file.
This library provides an interface where variables can be saved and restored
using a file in a file system accessible to the firmware.  It is expected
that a platform BDS library will use this library.  The platform BDS
implementation can decide which devices to connect and then to attempt to use
for saving and restoring NV variables.
