BaseTools/GenFv: Ensure the minimum pad file size for the FV with VTF
In case of the FV with VTF, the left size should be enough to add the
minimum pad file size (EFI_FFS_FILE_HEADER, 0x18). It prevents the build
error, "GenFv: ERROR 0006: invalid FFS file header checksum" caused by the
pad file overwriting some header data in VTF. This includes these updates
for CalculateFvSize() function.
1. If NumBlocks is not defined, ensure the minimum pad file size for the
left size (if the pad file is required as VTF is not bottom aligned at end
of block, insert EFI_FFS_FILE_HEADER to ensure the pad file size)
2. If NumBlocks is defined, report more clear error message (the required
fv image size = 0x%x. the set fv image size = 0x%x. Free space left is not
enough to add a pad file (0x18))
3. Remove MaxPadFileSize, which is reported when the taken size is same as
the total size. It can not be the actual left size to add an FFS file. It
causes confusion when referring to the build log (FV Space Information)
