[Serialization][wasm] Preserve wasm import metadata for SIL serialization Serialize/deserialize wasm import module/name for SIL serialization so inlined decls keep their import names. Otherwise, inlining a function with `@_extern(wasm)` would lose the import name and cause IRGen to emit an import from the default module "env".
