Avoid CHECK in fpdf_parser_decode.cpp (memcpy empty span)
Given a span of size N, memcpy(dest, &span[N], 0) ought to be a no-op,
but since we compute span[N] before checking for zero length, we hit
an assert. The correct idiom should be to create a sub-span, which
allows specifying N, but only when the size is 0.
