GM: common longitudinal actuator delay

[sshane]

This helped on the Acadia (https://github.com/commaai/openpilot/pull/25354), as well as the new Bolt EV/EUV where both cars have a large delay to initially start braking (similar to lateral friction we must overcome). The Escalade merged here also seems to have this same delay: https://github.com/commaai/openpilot/pull/27276

This PR adds this delay to all camera ACC cars (EVs do not have regen capabilities), and all ICE cars. The only platform this does not affect is the Volt.

Our Bolt with a low delay:

Waiting for a Silverado (camera ACC) and Escalade (ASCM) to try this and will merge.

Escalade: https://github.com/commaai/openpilot/pull/27406

Silverado also has similar lag: fe80a4e1cedec853|2023-03-20--20-24-23

Moving the Volt over as well, as the regen that is supposedly non-laggy isn't uniform across all speeds, and non-existent at low speeds, so the brakes are also reportedly laggy there.
