### Description

Pauses gas metering (i.e. `gasleft()` does not decrease as operations are executed).

This can be useful for getting a better sense of gas costs, by turning off gas metering for unnecessary code, as well as long-running scripts that would otherwise run out of gas.

:::note
`pauseGasMetering` _turns off DoS protections_ that come from metering gas usage.

Exposing a service that assumes a particular instance of the EVM will complete due to gas usage no longer is true, and a timeout should be enabled in that case.
