Copies the file attributes from @source to @destination.
Normally only a subset of the file attributes are copied,
those that are copies in a normal file copy operation
(which for instance does not include e.g. owner). However
if #G_FILE_COPY_ALL_METADATA is specified in @flags, then
all the metadata that is possible to copy is copied. This
is useful when implementing move by copy + delete source.
