BaseTools: Follow PI spec to update ExtendedSize in EFI_FFS_FILE_HEADER2

Browse Source 
for FFS data above 16 bytes alignment requirement.

PI spec requires FFS header to be at 8 bytes alignment to FV header.
And, FFS data alignment requires the beginning of the file data must
be aligned on a particular boundary, such as 1, 16, 128 bytes or above.
If FFS data alignment requires to be above 16 bytes, and FFS header
must be at 8 byte alignment, so FFS header size must be multiple of 8.
