Currently, the PE/COFF conversion routines in GenFw add a so-called
NB10 CodeView debug record to the image, and update the associated
directory entry in the PE/COFF optional header to contain its relative
virtual address (RVA) and size.
However, there are two levels of indirection at work here: the actual
NB10 CodeView record (which is simply a magic number and some unused
data fields followed by the NUL terminated filename) is emitted
separately, and a separate descriptor is emitted that identifies the
NB10 CodeView record as type EFI_IMAGE_DEBUG_TYPE_CODEVIEW, and records
its size. The directory entry in the PE/COFF optional header should
refer to this intermediate descriptor's address and size only, but
the WriteDebug## () routines in GenFw erroneously record the size of
both the descriptor and the NB10 CodeView record.
