Add LINUX_EFI_INITRD_MEDIA_GUID to our collection of GUID definitions,
it can be used in a media device path to specify a Linux style initrd
that can be loaded by the OS using the LoadFile2 protocol.
Move these defines to MdePkg from OvmfPkg as these are relevant to
non-OVMF targets as well.

+/** @file
+ GUID definition for the Linux Initrd media device path
+
+ Linux distro boot generally relies on an initial ramdisk (initrd)
+ which is provided by the loader, and which contains additional kernel
+ modules (for storage and network, for instance), and the initial user
+ space startup code, i.e., the code which brings up the user space side
+ of the entire OS.
+
+ In order to provide a standard method to locate this file,
+ the GUID defined in this file is used to describe the device path
+ for a LoadFile2 Protocol instance that is responsible for loading the initrd file.
+
+ The kernel EFI Stub will locate and use this instance to load the initrd,
+ therefore the firmware/loader should install an instance of this to load the
+ relevant initrd.
