EVM on WASM: Pay for gas to the gas limit

Context

Now transaction caller will have to pay for the gas up to the gas limit for the transaction. For simulation calls, this can be switched off (call argument to run_transaction). Currently there is no refund of unused gas and no refund of money. That will be implemented in a separate MR real soon.

Manually testing the MR

Use the unit tests. Use the CI.
