Include runtime API defs into metadata

[xlc]

Context: polkadot-js/api#4930

This will help client to query the available runtime APIs and able to invoke them with correct data.

This should be added to the sp_api::decl_runtime_apis! proc macro. It is essentially the same that ink! does for its messages minus selector generation.

Given that we're pushing more people to use state Call on the grounds that runtime api calls are on-chain upgradable (unlike rpc calls), we really do need to include them in the metadata. It's currently not a great dev experience that people code them up and then don't see them in the polkadot-js when they run it against their new chain.

I agree. However, the same is true for RPCs. So it doesn't make it worse at least.

[bkchr]

Yeah, you also only see available rpc calls, but that is all. You don't see parameters that you need to pass and that you get back.

[gilescope]

No but RPCs were never on chain upgradable so this is very much an awesomeness unlock.
