BaseTools: use GUID identifiable section for FFS alignment padding
Instead of using an anonymous section of type EFI_SECTION_RAW to pad
out the first aligned FFS section to its required alignment, use a
section with a dedicated GUID if the size of the padding permits it.
This allows for more flexibility when placing such FFS images in a
firmware volume, because we will now be able to remove padding rather
than add more, by shrinking the size of this section instead of
padding out the start of the FFS image to file alignment.
