wasm-linker: convert relocation addend to i32

Addends in relocations are signed integers as theoretically it could
be a negative number. As Atom's offsets are relative to their parent
section, the relocation value should still result in a postive number.
For this reason, the final result is stored as an unsigned integer.

Also, rather than using `null` for relocations that do not support
addends. We set the value to 0 for those that do not support addends,
and have to call `addendIsPresent` to determine if an addend exists
or not. This means each Relocation costs 4 bytes less than before,
saving memory while linking.
