* sp-api: Make the generated code act based on `std` in `sp-api`
Instead of letting the macro generate code that checks if the `std` feature is enabled, it will now
generate code that checks if the `std` feature is enabled for the `sp-api` crate. The old
implementation basically required that the crate in which the macro was used, had a `std` feature.
Now we don't have this requirement anymore and act accordingly the feature in `sp-api` directly.
* Missing feature!
