Jacob BarzeeandGitHub 06171037f0 Import alignment (#6426)
## What changed?
Make import formatting a part of the build, and test validity with
"ensure-no-changes" target

## Why?
So we never discuss import order again (hopefully)

## How did you test it?
its a build change, so the build will test it!

## Potential risks
As long as build works, the only thing I risk is the ire of coworker who
want imports to be different ;)

## Documentation
N/A

## Is hotfix candidate?
No
