[EVM] Dry-run function

[devbugging]

Closes: #5603

🍄 API Added Function

A new function for dry-running was added to the EVM Core contract:

    /// Simulates running unsigned RLP-encoded transaction using
    /// the from address as the signer.
    /// The transaction state changes are not persisted.
    /// This is useful for gas estimation or calling view contract functions.
    access(all)
    fun dryRun(tx: [UInt8], from: EVMAddress): Result {
        return InternalEVM.dryRun(
            tx: tx,
            from: from.bytes,
        ) as! Result
    }

The function takes the unsigned RLP encoded transaction and from address and dry-run a transaction to calculate used gas and result which is reported back to the caller.

This will be used for gas estimation and calling contract values by EVM gateway.
