PreExec tx return gasUsed and process slice parameters when invoke evm contract

[vantinfy]

Description

xuper/xuperclient.go: add field GasUsed when return the Transaction so that users can know how many gas they cost while pre-execute or post a transaction to the chain.

xuper/request.go: process slice parameters(they can be string slice, float64 slice or empty slice) when invoke evm contract.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Brief of your solution

Return gasUsed when post tx.
Process slice parameters when invoke evm contract.

How Has This Been Tested?

There is a evm function declare like this:

function createUsers(
        address[] calldata users, // create multiple users
        uint256[] calldata ids, // each user's id
    ) external {}

The previous code will parse request parameter users "[\"2462380BA1B39BB42AD9AECCAC7E91CB9D40AC27\",\"1A9BDAB96390EF0E4820519A95FCB96856202BB0\"]" and ids "[\"1\",\"2\"]" to string not the slice then lead to failure, the latest code will parse it correctly.
