These are core data structure which is shared with boot firmware and the
one's are moved here all are required by minidump driver .

If you follow here[1], i raised by concern to make this particular one's
as private and later to avoid confusion went with single header.
But if others agree, I will keep the one that get shared with minidump
as separate one or if relative path of headers are allowed that can make
it private between these drivers(which i don't think, will be allowed or
recommended).
