Note: The Temporary RAM memory size is being reduced from
64KB to 32KB. This still appears to be more than
adequate for OVMF's early PEI phase. We will be adding
another 32KB range of RAM just above this range for
use on S3 resume.
The range is declared as part of MEMFD, so it is easier
to identify the memory range.
We also now assign PCDs to the memory range.
The PCDs are used to set the initial SEC/PEI stack in
SEC's assembly code.
The PCDs are also used in the SEC C code to setup
the Temporary RAM PPI.

To help consolidate OVMF fixed memory uses, we declare this
range in MEMFD and thereby move it to 8MB.
We also now declare the table range in the FDF to set
PCDs. This allows us to ASSERT that CR3 is set as expected
in OVMF SEC.
OvmfPkgIa32.fdf and OvmfPkgIa32X64.fdf are updated simply
for consistency.

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).

PcdFlashNvStorageVariableBase64 is used to arbitrate between
QemuFlashFvbServicesRuntimeDxe and EmuVariableFvbRuntimeDxe, but even the
latter driver sets it if we fall back to it.
Allow code running later than the startup of these drivers to know about
the availability of flash variables, through a dedicated PCD.

This patch adds support for a debug console on the same port that is used
by SeaBIOS. This makes it easier to debug OVMF, because it does not mix
debug and serial output on the same device. It also makes it easier to
leave some of the debug messages on even in release builds.
To enable it, pass "-debugcon stdio -global isa-debugcon.iobase=0x402" to
QEMU.
The new mechanism is enabled by default, but a regular serial console can
be chosen by adding -D DEBUG_ON_SERIAL_PORT to the build options.

1) Remove section header comment blocks that do not provide any information
2) Combine PCDs listed in multiple sections into a single section that supports multiple PCD types to reduce maintenance overhead
3) Remove ModuleTypeList comments from [Includes], [Protocols], [Ppis], and [Guids] sections that do not properly describe the module type restrictions.
4) Clean up formatting of GUID structure declarations
5) Remove ".common" from section names if they are not required.
6) Order sections consistently as [Defines], [Includes], [LibraryClasses], [Guid], [Ppis], [Protocols], [PcdsFeatureFlag], [PcdsFixedAtBuild], [PcdsPatchableInModule], [PcdsDynamic], and [PcdsDynamicEx]

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.

* The MAIN FV with PEI & DXE can easily shrink and grow as needed
* The final output will now be OVMF.Fv rather than OVMF.fd
* The final output size will be a multiple of 64kb

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.
