PR24272, out-of-bounds read in pex64_xdata_print_uwd_codes

The fix here is to use an unsigned comparison for
    if (a->NumberOfRvaAndSizes > IMAGE_NUMBEROF_DIRECTORY_ENTRIES)

include/
	PR 24272
	* coff/internal.h (struct internal_extra_pe_aouthdr): Change type
	of SizeOfCode, SizeOfInitializedData, and SizeOfUninitializedData
	to bfd_vma.  Change type of SectionAlignment, FileAlignment,
	Reserved1, SizeOfImage, SizeOfHeaders, CheckSum, LoaderFlags,
	and NumberOfRvaAndSizes to uint32_t.
bfd/
	PR 24272
	* peXXigen.c (_bfd_XXi_swap_aouthdr_in): Use unsigned index.
	(_bfd_XX_print_private_bfd_data_common): Adjust for type changes.
