Now that the only functionality that remains in VirtFdtDxe is enumerating
the respective virtual I/O buses, it no longer makes sense to have a driver
that is shared between Xen domU and QEMU. So move the Xen I/O DT node
handling to a new driver, and update ArmVirtXen to switch to it.

We no longer care when VirtFdtDxe executes, since
- the driver sets no dynamic PCDs any longer, and
- the only remaining functionality centers on VirtioMmioInstallDevice()
and XenIoMmioInstall() function calls and FDT configuration table
installation.
So drop the A PRIORI declaration.

Add FdtClientDxe to the various platforms under ArmVirtPkg, so that the
drivers we will update to depend on the FDT client protocol in subsequent
patches will remain in working order.

Now that FatPkg is open source (and therefore can be included in the
EDK II tree) we build and use it directly.

This adds ARM support to the ArmVirtXen platform. As is the case for
AARCH64, the ARM port adheres to the ARM Linux boot protocol, i.e.,
it expects the address of a DTB describing the platform to be passed
in r2, and relocates itself at runtime to the actual load time memory
offset.

Beyond just changing the directly related lines in the FDF and DSC files,
we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib
instances as well, in the same patch. This is because the EmbeddedPkg
driver expects the SerialPortSetAttributes(),
SerialPortSetControl() and SerialPortGetControl() functions from
SerialPortExtLib, while the MdeModulePkg driver expects them from
SerialPortLib itself.
We cannot implement these functions in ArmVirtPkg's SerialPortLib
instances *before* flipping the driver, because it would cause double
function definitions in the EmbeddedPkg driver. We also can't implement
the functions *after* flipping the driver, because it would cause
unresolved function references in the MdeModulePkg driver. Therefore
we have to implement the functions simultaneously with the driver
replacement.

Now that GenFw correctly propagates the minimum alignment of the ELF
input sections to the PE/COFF binary, we can simply select 'auto'
alignment in the FDF Rule section instead of tweaking it by hand.
Also add the FIXED FFS attribute to the module types that may execute
in place. This enables a newly added optimization in GenFfs that strips
redundant padding, preventing excessive waste of FV space if the section
alignment is considerable (i.e., 2 KB or 4 KB)
