Support relative offsets when encoding spans
The relative offset is often smaller than the absolute offset, and with the LEB128 encoding, this ends up cutting the overall metadata size considerably (~1.5 megabytes on libcore). We can support both relative and absolute encodings essentially for free since we already take a full byte to differentiate between direct and indirect encodings (so an extra variant is quite cheap).
