feat: Mirror Node Contract Queries

[0xivanov]

Description:

A new MirrorNodeContractQuery class has been introduced to support EVM gas estimation and simulation. This query class provides two distinct types of queries:

1. MirrorNodeContractCallQuery – Executes a contract call and returns the result, simulating the execution of the contract.
2. MirrorNodeContractEstimateGasQuery – Estimates the gas usage for a contract call, allowing developers to understand the cost of executing a transaction.

The inputs for these queries match those of ContractExecuteTransaction, making it easy for developers to calculate the cost of a follow-up transaction.

The MirrorNodeContractQuery issues an HTTP request to the api/v1/contracts/call endpoint of the Mirror Node Web3 module, which supports both gas estimation and transient simulation of state-changing transactions. This enables accurate cost predictions and helps developers optimize their contract interactions before executing them on the network.

Few nits and needs a little design tweak. Otherwise LG.

LGTM.
