[PATCH 1/1] MdePkg: add definition of LINUX_EFI_INITRD_MEDIA_GUID

["Jeff Brasen" <jbrasen@nvidia.com>]

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.
