[BUG] Accel/Velocity values aren't coupled

[MisterZedd]

Describe the bug
Running AUTO_SPEED on my ZeroG Hydra build from an Ender 5 Plus gives me a reasonable velocity, but an acceleration nearly 4 times higher than what I've validated was possible myself with Eli's speed pattern (22k accel). Attempted to use the AUTO_SPEED provided values then AUTO_SPEED_VALIDATE instantly failed due to the toolhead barely moving after homing.

To Reproduce
Steps to reproduce the behavior:

1. AUTO_SPEED
2. View results
3. Input results into config
4. AUTO_SPEED_VALIDATE
5. Accel too high causes validation to instantly fail

@MisterZedd
This is probably due to accel and velocity and calculated separate from each other. This will be fixed in the next major update.
For now, running AUTO_SPEED_GRAPH will give you realistic results that you can use.
