deprecated_body_mover

BodyVelocity, BodyPosition, BodyGyro, and the other body movers.

The body movers are deprecated. LinearVelocity replaces BodyVelocity, AlignPosition replaces BodyPosition, AlignOrientation replaces BodyGyro, VectorForce replaces BodyForce and BodyThrust, AngularVelocity replaces BodyAngularVelocity, and LineForce with AlignOrientation replaces RocketPropulsion. Each needs an Attachment; no automatic rewrite.

Set its level in the [lint] table of alloy.toml, or for one file with --@alloy-lint.
