janherich 29ba5ab05a delta: Better delta build volume constraint check
Existing code uses very restrictive build volume constraint checking
with just narrow cone on top of fully cylinder for delta printers.

Code here implements more permissive and still safe build volume
constraint checks.

Kevin O'Connor afd1058af6 delta: Don't limit XY+Z moves to max_z_velocity
Scale the max_z_velocity limit by the amount of movement in the Z.
This should improve bed_mesh and vase mode prints on delta printers.

Kevin O'Connor 390d549c0c delta: Fix maximum halt velocity calculation
If an arm is nearly parallel to the bed then that tower's carriage may
have a velocity up to 3 times greater than the toolhead's maximum
velocity (relative to the print).  Take that into account when
calculating the stepper's maximum halt velocity.

This fixes some rare "No next step" shutdowns on delta printers.
