The UEFI spec requires that file positions are passed as u64 in
GetPosition() and SetPosition().
Check if the file handle points to a directory in GetPosition().
Provide a unit test for GetPosition() and SetPosition().
Fix Coverity warning CID 184079 (CONSTANT_EXPRESSION_RESULT).
Add comments.
Fixes: b6dd577737 ("efi_loader: use correct types in EFI_FILE_PROTOCOL")
