Support Carryall pickup orders on deployed units

[pchote]

We currently don't support targeting deployed tick tanks / juggernauts / sensor arrays / etc. It would be a nice quality of life improvement if Carryalls could be ordered to pick up these deployed units, with the unit undeploying once the carryall arrives.

This could be done by changing Carryable.LockForPickup to interact with GrantConditionOnDeploy (via IWrapMove or a new interface), and returning an enum with values for "locked", "will lock, soon", and "failed" instead of a bool so PickupUnit can wait for the animation to complete.
