GM: Bolt EUV port

[JMPZ11]

Basic port for vehicles with ACC, but without an ASCM (or accessible radar points)
Bolt EUV and Silverado have been added; Suburban, Tahoe 2022 Bolt LT2, GMC Sierra (after GM VIN query) are now simple ports.

EDIT: Will break down into parts, but wanted to get the final appearance down and get feedback on some choices.

Depends on two unmerged PRs:

• Panda: GM: Add support for cam harness & stock ACC panda#962
• OP: GM: parse low and manumatic gears #24764

For testing purposes, these PRs have been pre-merged / referenced - This branch builds and passes pre-commit

Includes Silverado and Bolt EUV - tunes both require review

Checklist

• added entry to CarInfo in selfdrive/car/*/values.py and ran selfdrive/car/docs.py to generate new docs
• test route added to routes.py

Let's break this up into individual car ports. I'd recommend just removing one from this PR and making a new PR once we get this new platform merged with a single car.

Thanks Adeeb, Sounds like a plan - before I do too much splitting (I'm happy to break it down to more easily testable chunks) I wanted to make sure the approach was acceptable. I'll throw PR comments with things about which I have questions - if that's ok

panda and this PR should be ready for final review!
