fix(cmd/rpc): Rework all methods that take variadic params

[vgonkivs]

Unfortunately, go-openrpc can't handle methods that accept variadic params. We should rework all these methods to accept the Options struct(as was proposed in #2630)

[Wondertan]

We should aim to fix variadics so that we have non-breaking way to add Options struct to each method

[distractedm1nd]

We don't have any methods that use variadic params on our RPC so I think this can be closed

[Wondertan]

No, we want variadics for non-breaking options

@Wondertan Can we start working on this?

[Wondertan]

This is a tricky one, but I believe it is valuable, so I would happily review it

@Wondertan is there any specific endpoints need to support non-breaking options ? From my review, might be state package or anything else in mind?
