🔷 [Epic] Access RPC from indexerLogic

[pkudinov]

Description

Developers should be able to run view_call on their smart contracts. This epic is to implement context.viewCall(contract, functionName, optional_block_height) which returns unbase64 result.

As a source for view calls, we need to use archival RPC or preferably ReadRPC.

Additionally, we can support deserialization with borsh schema.
