wasm: correctly generate relocations for type index
Previously we could directly write the type index because we used the
index that was known in the final binary. However, as we now process
the Zig module as its own relocatable object file, we must ensure to
generate a relocation for type indexes. This also ensures that we can
later link the relocatable object file as a standalone also.
This also fixes generating indirect function table entries for ZigObject
as it now correctly points to the relocation symbol index rather than
the symbol index that owns the relocation.
