include: pe.h: add signature-related definitions
The index (IMAGE_DIRECTORY_ENTRY_SECURITY) in a table points to
a region containing authentication information (image's signature)
in PE format.
WIN_CERTIFICATE structure defines an embedded signature format.
Those definitions will be used in my UEFI secure boot patch.
