feat: filtered queries in contracts

[DCNick3]

Description

• remove QueryWithParameters
• move all parameters to ClientQueryPayload (was QueryPayload before, stored inside SignedQuery); SignedQuery now equivalent to QueryWithParameters<SignedQuery>. All the parameters are now scale-encoded and versioned instead of being passed as query parameters
• make SmartContractQuery, which is now equivalent to QueryWithParameters<QueryBox> that was used before, but has filtering support
• move all the post-processing (filterting, sorting, pagination, batching) to a single function (LazyQueryOutput::apply_postprocessing), introduce a new type for a post-processed query output
• add an integration test using the filtering (ProcessedQueryOutput)
