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.
